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.

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

O processo de ensino aprendizagem da educação no trânsito por meio da construção de um personagem heróico

This research project aims to study the relationship between the myths and the automobile, the contributions to the literature of fairy tales and the possible contributions of the heroes of fairy tales can bring to the process of teaching and learning defensive behavior in traffic. Traffic is a phenomenon so common to modern societies that often do not pay attention to their relevance as synonymous with social space and contains diversity of people and behaviors. To counter the image of fatalistic accidents and transgressions, will support us in the virtues of the hero figure to culminate in a collective tale in which children want to rethink their behavior, becoming citizens, with a more preventative and better quality of life. The research will be held in four rooms of elementary school in a city public school that serves children from families of the urban popular classes. The research will seek to analyze how the design of transit for the children and what the increase attributed to the theme, after the establishment of a collective story

Relações entre os acidentes de trânsito e a precipitação na área urbana de Rio Claro (SP)

Traffic accidents are considered a concern for both public agencies and for researchers that are seeking alternatives to reduce the number of deaths and incidents. Thus, the aim of this work was to compile a database of traffic accidents recorded for the 2° Sub-Grouping of the Fire Department of the city of Rio Claro (SP) during the years 2008 to 2010 and related to rain. The result allowed profiling of traffic accidents, recognize critical areas and correlate the rain as an interference factor in the occurrence of traffic accidents in Rio Claro (SP)

Caracterização in vitro de técnica biomagnética empregando magnetômetros 3D para avaliar tempo de trânsito esofagiano

The biomagnetic techniques use different magnetic field detectors to measure parameters of the human physiology. Those techniques present the advantage of being noninvasive and radiation free. Among them we can show up the Superconducting Quantum Interference Device (SQUID), the Current Alternate Biosusceptometry (ACB) and, more recently, the employment of anisotropic magnetoresistive sensors. Those magnetic sensors have a low cost and good sensitivity to measure different physiological parameters using magnetic markers. The biomagnetic techniques have being used successfully through study on the characteristics of the gastrointestinal tract. Recent research, the magnetoresistors were used to evaluate the transit time and localization of magnetic sources in different parts of the gastrointestinal tract. The objective of this work is the characterization, with in vitro tests, of a biomagnetic instrumentation using two 3-axis magnetoresistors arranged in a gradiometric coplanar setup to evaluate esophageal transit time, analyze and compare the results of experimental signals and the magnetic theory, as well as evaluate the instrumentation gain with use of tri-axial sensor front to the mono-axial sensor. The instrumentation is composed by two three-axis sensing magnetometers, precision power supply and amplifier electronic circuits. The sensors fixed in a coplanar setup were separate by distance of 18 cm. The sensitivity tests had been carried through using a cylindrical magnet (ø = 4 mm and h = 4 mm) of neodymium-iron-boron (grid 35). The tests were done moving the permanent magnet on the sensors parallel axis, simulating the food transit in... (Complete abstract click electronic access below)

Biosusceptometria de corrente alternada para avaliação do trânsito gastrintestinal de alimentos líquidos em ratos

The gastrointestinal tract is the main route of nutrients absorption and drugs delivery. Is important to know the parameters related to the tract, like gastric emptying and gastrointestinal transit, in order to better understand the behavior of different kind of meals or drugs passing through the GIT. Many techniques are used to study these parameters, such as manometry, scintigraphy, phenol red, activated charcoal and carbon-13 reading. However, these methods use radiation, are invasive and require animal sacrifice. As an alternative proposal, the Alternate Current Biosusceptometry (ACB), a magnetic technique, has proved to be effective for these studies with small animals, in a noninvasive way, low cost, radiation free and avoiding the animal death. Associating the ACB to magnetic micro or nanoparticles used as tracers, it is possible to observe the meal behavior inside of the GIT. Focusing meanly on liquid meals digestion, this paper had the objective to evaluate the efficiency of the ACB technique in gastric emptying and gastrointestinal transit evaluation of liquid meals in rats. To perform the experiments, magnetic nanoparticles (ferrite, MgFe2O4) were used on a 1,5 ml solution introduced by gavage on similar weight and age rats. The sensor made by 2 pairs of coils, capable of generating and detecting magnetic fields, creates a field on the interest place and when this field is in contact with the marked meal, it changes, resulting on a variation of the measured voltage. The voltage variation is analyzed and is obtained a particle concentration on the interest region. The results showed that is possible to apply the ACB technique on the GIT evaluation of liquid particles digestion, gastric emptying and meal cecum arrival time curves were obtained and from that, is possible to observe a pattern of gastrointestinal transit. Both mean process time values were acquired, proving the technique capability of ...

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
