Demanda energética em diferentes manejos de solo e híbridos de milho

This study aimed to account the energy balance of six different farming systems: CMT (minimum tillage with transgenic corn); CMNT (minimum tillage with non-transgenic corn); PCT (conventional tillage with transgenic corn); PCNT (conventional tillage with non-transgenic corn); PDT (no-tillage system with transgenic corn) and PDNT (no-tillage system with non-transgenic corn). The study was carried out at the Experimental Farm Lageado FCA/Unesp, Botucatu - SP. The energy balance was performed by subtracting the total energy inputs by the total energy output. Energy efficiency was calculated by dividing the total energy output by the total energy inputs. The total values ​​of energy inputs and outputs were expressed in MJ.ha-1 (mega joules per hectare). To calculate the energy inputs were accounted the fuel consumption and lubricants, depreciation energy of machinery and implements, manpower and agricultural inputs. The energy outputs were calculated according to the maize yield. The result shows that the system PDT was the system that had better energy efficiency and the system that had the lowest efficiency was the PCT system. The system with lower energy demand was the PDT and the greatest demand was PCNT.

Eficiência energética da produção de café orgânico na região sul de Minas Gerais

In this study, organic coffee production systems energy efficiency was estimate. So, an itinerary technical was built since the deployment phase up to the organic coffee production. The inputs used (labor, machine hours, pesticides, fertilizers, etc.) converted into energy units, quantified the energy input, while the production of organic coffee beans benefited was constituted the energy output. Data collection was based on an intentional and non-probabilistic sampling. Nine farmers were interviewed whose main source of income was the coffee production and had keep records of the culture data. The balances were positive, with an energy yield of 626.465MJ.ha-1, compared to an energy expenditure of 112.998MJ.ha-1 during the crop cycle. It is concluded that organic coffee production is energy efficient.

Políticas e desenvolvimento do estado de Mato Grosso após abertura comercial: análise da visão de dois empresários atuantes no setor

After realizing two interviews, with distinct managers/businessmen working in the cotton industry, the objective is to put in evidence the political, economical and social factors that contributed to the formation and configuration of the Mato Grosso state, after the trade liberalization that occurred in the early 90's, it's effects and consequences in the eyes of the interviewed. The study of public policies is primordial to the discovery of the configuration of determined place, evaluating advances and possible errors in the social, economical and environmental areas. Through the analysis of the interviews it has been found that the urban centers have been developing with a direct link to the industrial activities related to agriculture and that the labor work force have also been attracted because of these changes, and as a consequence this labor force is now becoming more specialized to be able to accompany the jobs requirements in the industry. Analyzing the interviews, it is possible to highlight some information about the development of Mato Grosso, among those the following factors and public policies. The creation and expansion of the cities in the state are possible through public and private investment in infrastructure the socioeconomic development of the state is linked with the advances made in the private sector that grows because of advances made in crops technology in contrast to the occupation of the cerrado, in relation to the cotton crops. The problems that Mato Grosso is facing are mainly linked to the region infrastructure, that can count on investment plans to transportation and production flow that dates before the globalization era. The pattern that is seen today with top of the line agricultural production, big monoculture with high productivity and the arrival of multinational giants, was implanted because of two important events: the trade liberalization in the 1990's and the cambial depreciation in the 1999's...

Estudo da cadeia petrolífera no Brasil: uma contextualização das tendências da indústria nacional e das relevâncias do PRH48

In the past few years, the Brazilian oil and gas sector had a considered growth, gaining enough relevance at international level, and being extremely important for the Brazilian socioeconomic development. However, the sector is still limited due to technical deficiencies. This work aims to conduct a current study, comprehending the entire oil chain, since it is possible to mention the Brazilian market updates on this context. To support this study, the historical development of the Brazilian petroleum industry was presented and the main stages of the production process were exposed with an emphasis on exploration and production phases. The new technologies developed for deepwater extractions, such as the pre-salt regions, were also discussed and, in the end, the relation of this growing market with the opportunities of the Human Resources Program of n. 48 was highlighted. This program identifies the market's actual needs and it's scarce's areas with the purpose of building capacity and qualified workforces, since it is also aimed, in a national level, a self-sufficient human resources for the sector

A dança da situação: refletindo sobre os elementos que compõem a linguagem estético-expressiva presente na construção da obra A Mão do Meio - Sinfonia Lúdica, coreografada por Denise Namura e Michael Bugdahn

A Cie. <<à fleur de peau>>, fundada em 1988 pela brasileira Denise Namura e pelo alemão Michael Bugdahn, sediada na França, desenvolve uma linguagem estéticoexpressiva própria, caracterizada por integrar áreas artísticas distintas, como a dança, as artes circenses, o teatro e a mímica. Tal confluência decorre da formação de ambos os fundadores, atuais diretores e coreógrafos da companhia de dança-teatro. O intercâmbio dessa companhia com o Brasil é constante, incluindo apresentações de seus espetácul os, coreografias para outras companhias e oficinas. Em uma de suas vindas à cidade de São Paulo, no ano de 2013, tivemos a oportunidade de entrar em contato com a pesquisa de linguagem da Cie. Em 2014, os fundadores foram convidados a coreografar um espetáculo infantil para a Cia. de Danças de Diadema, localizada no ABCDMR paulista. Este estudo partiu do interesse em conhecer o trabalho desenvolvido por Namura e Bugdahn. A partir desse encontro, pudemos observar, relatar e refletir sobre como ocorreu a tran smissão dessa linguagem estético-expressiva no processo de criação do espetáculo A Mão do Meio - Sinfonia Lúdica aos bailarinos da companhia diademense. Para tanto, acompanhamos os ensaios referentes ao espetáculo durante os períodos anterior e posterior à pré-estreia e à estreia oficial do espetáculo. Posteriormente, foi possível tecer outra reflexão, dessa vez sobre os elementos teatrais componentes dessa linguagem, que a tornam diferente em relação ao processo de criação artística e apresentação da obra
