Potencial produtivo da cana-de-açúcar sob irrigação por gotejamento em função de variedades e ciclos

This study aimed to evaluate the yield potential of different varieties of sugarcane under drip irrigation in two growth cycles. A trial was set up in October 2006 at Jaú region (São Paulo state, Brazil), in an experimental field with a eutrophic Ultisol. The experiment was conducted in randomized complete blocks with factorial treatment structure 8 x 2, constituted by eight sugarcane varieties and two crop cycles, with six replicates. Stalk productivity (TCH), sugar productivity (TPH), juice quality traits and water use efficiency in relation to stalk productivity were evaluated in each crop cycle. It was observed that varieties of sugarcane respond differently to full irrigation, and this response is influenced by climatic conditions of the agricultural year. In this study, only the first evaluation cycle (plant cane) was decisive to differentiate the performance among the varieties. The varieties IAC91-1099, IACSP96-3060, RB855536, RB867515 and SP85-1115 showed higher agro-industrial yield potential and less consumption of water and can be recommended for the management of production under drip irrigation.

Análise de corrosão, dureza e fratura de conjuntos implantes / componentes protético de Titânio c.p., após serem submetidos a ciclos de fadiga em um meio fluoretado com diferentes PH

Atualmente o titânio é empregado como biomaterial devido à sua biocompatibilidade e resistência à corrosão. Entretanto, íons fluoretos, freqüentemente empregados em dentifrícios bucais, podem interferir no processo de corrosão. O objetivo deste estudo foi analisar a influência de um meio fluoretado com diferentes pH nas propriedades mecânicas e na resistência à corrosão dos conjuntos implantes/componentes protéticos à base de Ti c.p., a partir dos testes de fadiga, microscopia eletrônica de varredura (MEV) e dureza. Foram simulados cinco anos de uso regular de meios de higiene oral com conteúdo de 1500 ppm de NaF, com dois diferentes pH, 7,4 e 5,3, mediante imersão das amostras nesses meios durante 184 horas e também em água destilada, grupo controle. As amostras foram testadas num durômetro Micromet 2001 (500gf/30s). Os dados dos testes de dureza foram analisados pelo teste de Wilcoxon, demonstrando que as amostras sofreram influência negativa na dureza após a ação dos íons fluoreto. Entretanto, essa influência não ocorreu nos testes de fadiga realizados em uma máquina de ensaios mecânicos MTS-810, fixada a 100.000 ciclos, 15Hz e programada com força de fadiga a 150 N. Pela análise de MEV foram constatadas evidências de corrosão na superfície das amostras após ação de íons fluoretos, entretanto pelo EDS não se verificou incorporação de íons fluoretos sobre a superfície dos conjuntos. Concluiu-se que a concentração de flúor e o pH das soluções não exerceram influência nas propriedades mecânicas.

Feiras de negócios: o estande que fala : o Relações Públicas no planejamento estratégico de estandes para Feiras de Negócios, da estruturação à mensuração de resultados

All the time, organizations are seeking ways to relate to their audiences, in order to become stronger institutionally and merchandising. In the era of information technology contacts occur increasingly in virtual form, minimizing the face-to-face. Thus, this study contextualizes the trade fairs as a way to bring business relations / public interest in a real environment and provides the friendly atmosphere, much as in a short time, the company with a large amount of their customers, potential customers, partners, suppliers, and other audiences that may be interesting. However, shows that for the success of these events is a necessary strategic planning, so that subsequent implementation is possible to measure the results. It also envisions the trade fairs getting a new format, that is, their commercial character to give the space for the relational as a way to bring more awareness to organizations and to strengthen ties with their audiences. This beneath the optics of Public Relation as the appropriate professional to manage relationships and therefore be the strategist of the company's participation in a trade fair

Avaliação mecânica da colagem estrutural entre compósitos poliméricos e materiais metálicos utilizados em dutos petroquímicos

The development of technology for structural composites has as one of its ends form a set of materials that combine high values of mechanical strength and stiffness and low density. Today, companies like Embraer and PETROBRAS and research institutions like NASA, working with these materials with recognized advantages in terms of weight gain, increased performance and low corrosion. We have developed a systematic study to determine the bond strength between composite carbon fiber / epoxy and fiberglass / epoxy laminate both bonded to a carbon steel which are widely used in the petrochemical industry and repair. For morphological evaluation and bonding between materials of different natures, ultrasound analysis, optical microscopy and stereoscopy were performed. To simulate actual conditions, the composites were subjected to conditioning by using heat shock temperatures from -50 to 80 ° C for 1000 cycles for composite carbon fiber / epoxy composites and 2000 cycles for fiberglass / epoxy . The use of composites studied here proved to be efficient to perform repairs in metallic pipes with application petrochemical, as when exposed to sudden changes of temperature (-50 ° to 80 ° C) cycling at 1000 to 2000 times, its mechanical properties (shear and tensile) practically do not change

A terminologia das Feiras de negócios: análise das variantes linguísticas

The trade fair industry has great relevance in the national and international economic environment and it is constantly expanding. The general objective of this work is to analyze the main linguistic variants found in the trade fair terminological set. Our research is based on the theories of Cabré (1993, 1999), Barros (2004), Krieger & Finatto (2004), Alves (2007), Barbosa (2009), Dubuc (1985), Berber Sardinha (2004), Babini (2006) and Faulstich (1998, 2001). For this work we constitute two corpora of specialized texts, one for English language and another for Portuguese language. Successively we performed a collection of terms using software for corpora processing. These terms were organized into two notional systems, one in English and another in Portuguese. Then we analyzed the main types of variants found in our terminological set. Among them, those who had higher productivity are the lexical variants, followed by graphical, morphological and syntactic variants.
