Características da cana-de-açúcar in natura e hidrolisada com cal virgem em diferentes tempos de estocagem

Our objective was to evaluate the chemical composition and in vitro digestibility of dry matter of hydrolyzed sugar cane in different storage times. We conducted the trial in the Forage Sector at UNIFENAS, campus of Alfenas (MG) in 2010. The data were analyzed as completely randomized design in factorial scheme 2 (sugar cane without lime and hydrolyzed with 1.0% of lime, basis of fresh matter) x 6 (six times of storage: 0, 24, 48, 72, 96 and 120 hours), with three replicates. The sugar cane stored without lime showed lower dry matter (DM), crude protein, neutral detergent fiber and acid detergent fiber contents compared to hydrolyzed sugar cane. However, the hydrolyzed sugar cane showed higher contents of organic matter (OM) and total digestible nutrients. We reported higher in vitro digestibility of DM and OM when the sugar cane was not hydrolyzed. This can be explaining by better chemical composition of sugar cane without lime. The storage of sugar cane without lime shows results more interesting because the chemical composition and digestibility is better than hydrolyzed sugar cane. So, we not recommended using lime on the sugar cane. Moreover, the sugar cane without lime can be stored until 96 hours after cut.

Estudo de tempos e métodos em uma microempresa prestadora de serviços de usinagem mecânica

This paper aims to survey data to analyze the productive capacity of a machining process of rolling bearings by methods-time measurement, in order to identify its bottlenecks and propose improvements in the system. The production times at the company are not known, the method of separation of operations and identification of its activities and the timing of production times and setup become points of departure for this paper. The results from this method of analysis provide clarity in identifying system weaknesses and by them it was possible to carry out the proposals for improvement in some process steps. The implementation of the improvements was not performed, but with the goals of this work was made possible to raise relevant information of the analyzed system

Avaliação do comportamento da temperatura na massa deresíduos com diferentes tempos de disposição no aterro sanitário de Rio Claro - SP

The present work investigates solid waste temperature behavior in different depths in two cells in the Rio Claro-SP city’s sanitary landfill. One of the cells is in operation with waste disposal beginning about one year ago. The other one is located in an closed area and contain waste disposed from five to seven years before. Measures were also made in an area that have no disposed waste in order to collect reference values. The data were obtained every fifteen days. The temperature results shows higher values in the operating cell, with maximum 38,1 °C in a depth of 4,0 m. In the closed cell the highest values were 36,3 °C in a depth of 8,5 m. The highest temperature values were obtained in the operating cell due to wider substract availability that indicates a more intense biological degradation activity. With three meters depth, the temperature results were 36,6 °C in the operating cell, 33,8 °C in the closed cell and 24,5 °C in the reference area. Therefore the temperature can be used as a biological activity indicator in sanitary landfills, supporting biogas studies

Estudo da influência da aplicação do fluido de corte no torneamento da liga de alumínio AA7075

One of the ways to minimize the effects of unproductive time caused by tool wear can be achieved by introducing an efficient system of lubrication and cooling in the process. However, in the last decade the research had the goal to restrict the maximum use of refrigerants and / or lubricants in metal-mechanical production. The important factors that justify this procedure include the operational costs of production, ecological issues, and the legal requirements of environmental conservation and preservation of human health. The purpose of the proposed work is the study of machining by turning with the focus on the influence caused by the application of cutting fluid in several ways of application (abundant and MQF) and also by comparing the results obtained by machining without the presence of fluid . For this purpose, the turning tests are conducted using an aluminum alloy (AA 7075). The response variables to be analyzed were obtained from the roughness (Ra and Ry), the stresses presented (VB) and their progression in relation to the cutting length achieved, the type of chip formed, in addition to changes in the degree of finish (roughness) presented by the turned parts. The results of this study should provide more detailed information about the actual influence of cutting fluids in turning this alloy, which are characterized by high rates of deformation when the formation of damaging your chip machining and also the quality of surface generated. Therefore, it is expected to provide subsidies to promote the optimization of machining this alloy making the most of the role of cutting fluid

As relações públicas e a gestão da comunicação integrada em tempos de crise: uma análise sobre o caso Ades no Facebook

This paper aims to understand so that organizations in times of crisis - exposed to social media, especially Facebook - they conceive strategies to minimize any factors that shake with your credibility, image and reputation. There for, the case study on the crisis experienced by Ades brand in March 2013 was chosen. The methodology of the work consists of bibliographic research and analytical as well as the presentation and case study, covering the concepts of Marketing, Public Relations, Social Media, Reputation Management and Image, Branding and Integrated Communication. This work was divided into four chapters that present the management of communication in the digital age, the presentation of the global Unilever brand and it brand Ades; exposure to the crisis and its repercussion and an analysis of the case under the stance of public relations, in this order

Estudo de tempos e temperaturas de sinterização na obtenção da liga NiTi por metalurgia do pó

The nickel-titanium alloys are very attractive and so it is widely used in industry, engineering applications in general and also in biomedical and dental applications. Besides showing the shape of memory effect, biocompatibility and superelastic, the alloy commercially known as Nitinol, has excellent mechanical properties. Most devices used in Brazil have been produced nationally, but using imported material is also necessary, which shows the need of produce the alloy nationally. In this study we have investigated the influence of sintering temperatures and times to obtain nickel-titanium alloys by powder metallurgy alloys and the characterization of the precipitated intermetallic phases by using the post-mix of elemental nickel and titanium in proportion of 49.5% Ti - 50.5% Ni. The samples were sintered at 930ºC for periods of 30, 40 and 50 hours and were characterized by optical microscopy using metallography and x-ray diffraction. The results of the study show that the 50 hours sintering time was the most suitable time for obtaining the alloy, observing a low volume of precipitated intermetallic phases and absence of Ni and Ti residuals
