TROCAS GASOSAS EM PLANTAS DE CANA-DE-AÇÚCAR INOCULADAS COM GLUCONACETOBACTER DIAZOTROPHICUS E SUBMETIDAS AOS ESTRESSES SALINO E HÍDRICO

The sugarcane crop isconsidered moderately sensitive to environmental stresses, which results in reduced growth and lower productivity. In addition, there is a need for the application of high doses of nitrogen fertilizer. A potential and agroecologically correct alternative is the use of nitrogen-fixing endophytic bacteria, such as Gluconacetobacter diazotrophicus. However, under conditions of abiotic stress the benefits from this plant-endophyte association can be altered due to the physiology of stress response. The objective of this work was to study the effect of inoculation of G. diazotrophicus by means of the evaluation of the parameters of gas exchange, in sugarcane plants submitted to salt and water stresses. The rates of stomatal conductance, transpiration and liquid photosynthesis were evaluated by means of a portable infrared gas analyzer (IRGA). The results showed that the presence of the bacteria may alter the rates of stomatal conductance and transpiration, interfering in the physiology of response to salinity and drought. Keywords: Endophytic bactéria. Stomatal conductance. Transpiration. Salinity. Drought.

ANÁLISE COMPARATIVA DA VIABILIDADE DE ADESÃO DA TARIFA BRANCA PARA SUBGRUPOS DE CONSUMIDORES B1, B2 E B3 DE ENERGIA ELÉTRICA

In many parts of the world, the concerns with the supply of electricity and the consequences regarding environmental issues related with greenhouse gas emissions have arouse the adoption of governmental policies which encourage a foreseen increase of renewable energy sources. As a result, renewable energy sources have shown a fast growth in production of electricity, by 2,8% a year between 2010 and 2040. After the renewable generation, Natural Gas and Nuclear Energy will be sources of fast growth. Once electric systems are always subject to possible contingents, it is of pivotal importance that they are capable of operating in a way of providing the highest reliability level desired by consumers of electricity. Within this context, the aim of this work is to present the regulatory structure and accession technical to the white fare. Bibliographic research and case study techniques were used to simulate consumer load curves classified in group B, subgroup B1, B2 and B3 with the exception of the low income and SMC category. The research establishes the comparison of white fare and conventional tariffs, seeking to situate the feasibility of choosing the current tariffs. Finally, the work presents the energy consumption behavior of each subgroup of group B, the consumer modulation capacity and the application of the tariff to residential and commercial consumers, in order to get the economic comparative analyzes already exposed. In a more in-depth analysis of the results, it appears that if consumers practiced really effective load modulation, only the discounts offered are not enough to choose their daily routine.

DESENVOLVIMENTO DE UM SISTEMA DE CARACTERIZAÇÃO DAS CARGAS COMO AUXÍLIO DE DECISÃO NA ADESÃO DA MELHOR MODALIDADE TARIFÁRIA

The Brazilian electricity sector currently needs a technological and sustainable reform to boost the country development. At the same time, restructuring has been taking place around the world through the insertion of alternative energy sources, new tariffs systems, the adaptation of new technologies and habits changes that have an impact on energy consumption. The consumer attitude towards the electric power consumption is a fundamental factor against the economic, social and environmental perspectives, praising the importance of having a population engaged and aware about their consumption acts impacts. Starting from the point that access to information and knowledge is the way to achieve significant changes, this study presents the development of a system for load characterization in white, conventional or horo-seasonal tariff modalities - according to consumer classification - in order to obtain comparison parameters that aid in the decision making as to the adhesion to the most appropriate tariff modality. The research techniques used were the bibliography and case study based on energy loads from a supermarket in the city of Vitoria, ES. In this way, after receiving the input parameters, load configuration and consumption schedules, the system generates the values associated to the tariffs rates and tariff calculations. Furthermore, the system presents the monthly load curve and the electric consumption profile of an installation from the survey of equipment possessions and use habits. The system developed based on the loads in a supermarket and proved successful in processing the demand curves. Keywords: Demand Curve. Tariff Modalities. Consumption Management

A INFLUÊNCIA DA GRANULOMETRIA DO CARVÃO NO PROCESSO DE CEMENTAÇÃO SÓLIDA DO AÇO AISI / SAE 4140

One of the major concerns of all researchers in steels industries is improve the performance of materials to gain security, efficiency and lifetime. Carburizing using a solid mixture of carburizing ingredients is the older and applied thermochemical treatment to change physical, mechanical and chemical properties of materials. In this context, investigations were carried out to study the effect of size of the carburizing solid mixture on the mechanical properties, hardness and strength, of steel AISI/SAE 4140. The research was basic in nature, but with immediate utility and useful for use in other investigations or technologies. Nine tensile and hardness tests were evaluated in tests. It was observed that, the mechanical properties of steel were improved by carburizing. The size of carburizing solid mixture had effect only on the result of strength of steel. Smaller sizes had the better results of strength. Also, the results revealed that, there are a size (Mesh 16) from which there is no more improvement on strength. Keywords: Steel. Carburizin. Size.
