Comportamento ingestivo de bovinos mantidos em pastos de Brachiaria brizantha cv. Xaraés manejado em diferentes alturas de pastejo

This experiment was conducted to evaluate the effect of grazing heights on daytime behavioral activities of Nellore beef cattle in the rainy season. The experimental area was 12 hectares divided into paddocks of one hectare each. The treatments consisted of four defoliation heights (15, 30, 45 and 60 cm) in pastures of Brachiaria brizantha cv. Xaraes with three replicates each. It was used the continuos grazing method, with variable stocking rate. Forage samples collected on the plots were sent to the laboratory for separation of the botanical components, weighing and determination of dry matter, with the material collected by simulated grazing. The variables: grazing time, idle time and ruminating time were evaluated for 12 consecutive hours on days 15 and 16 February 2011, considering the morning and afternoon periods. It was used a completely randomized design. The height of the canopy significantly influenced the daily grazing time and ruminating time, with a quadratic response as a function of time of defoliation. The bite rate decreased as a function of heights studied. However the chemical composition of the material collected by simulated grazing did not differ between treatments. Xaraes grass swards grazed at around 45 cm height provide greater ease of apprehension by grazing cattle.

Estudo de um método automatizado para o cálculo da profundidade de visualização dos equipamentos de ultrassonografia

Ultrasound is the term that describes the sound waves with higher frequencies than human hearing. Ultrasound used in medical diagnosis is a modality based on the use of sound energy and the acoustic properties of the various parts of the body to produce images of stationary and moving tissues. However, despite the ease of use and security that this modality offers for not using ionizing radiation, one should ensure the accuracy and optimum performance of the equipment, which results in precise diagnoses. To accomplish that, periodic quality control tests must be performed, which include: physical and mechanical inspection of the equipment, image uniformity, depth of penetration/visualization, accuracy of distances, axial and lateral resolution, dead zone and doppler sensitivity. This work intends to study a computerized method for calculating the depth of penetration of ultrasound, comparing it to the observerdependent method currently used. The images were collected during the quality control tests of ultrasound equipment. The results of the comparison between the visual and computerized methods were not conclusive for selecting the safest methodology for obtaining the depth of visualization

Proposta de diretrizes embasadoras para introdução de sistemas de medição de desempenho em empresas de projetos de instalações prediais

The civil construction in Brazil has grown a lotover the last years. This has caused a greater competition between companies of the sector. A little difference in quality in service or product a company offers can determine their success in the market. There is a growing demand for tools that optimize processes and bring greater quality to each activity in these companies. Performance measurement systems make it possible to control process efficiency and effectiveness using performance indicators. Considering this need, the paper before you has the objective of creating basic guidelines to introduce performance measurement systems inbuilding installations project companies. A theoretical reference is presented to describe organizational aspects of project companies along with performance measurement systems characteristics. Using a qualitative research methodology, a study case was executed with interviews, observation and document analysis as evidence sources. In the study case, limitations where identified, such as, high degree of product and process flexibility, dependence on subjective analysis for decision making and lack of specialized information systems. Considering the theoretical reference and the study case,the proposed guidelines intend to ease and guarantee greater chances of success when implanting one of these systems

A internet e os públicos empresariais: manual prático de relações públicas na grande rede

The ease and convenience provided by the Internet allow for the communication between the organization and its stakeholders to become rapid and effective. This fact can be good both for the organization and for the public. Keeping this in sight, the Internet as a public relations tool for communication between the organization and its stakeholders is the theme discussed throughout this study. Through bibliographic and exploratory research, this paper aims at pointing at effective tools afforded by the Internet that can be used by Public Relations. These tools can promote the relationship between organizations and its publics inserted on the Internet. In this way, the organization can influence publics in its favor. The present work investigates what strategies the Internet can contribute significantly to the field of Communication despite the fact that it is not able to completely replace traditional media

Avaliação da política curricular paulista: perspectiva docente sobre os cadernos do professor e do aluno

The current curriculum policy of the Secretary of Education in the State of Sao Paulo introduced into the education environment the Registrar of Teacher and Student - support material to ease the teacher's work and the student's learning, in order to address all the curriculum components created as strategy of learning. The resulting guidelines that aim to transform the everyday policies of educational institutions and the individuals who compose them, are incorporated into the school experience. These decisions, however, do not transfer into life outside the learning environment nor are they translated into the work of the teachers exactly as their creators intended. Thus, in order to better understand the curriculum policies introduced by the Registrar in schools, it is essential to comprehend the viewpoint of the teachers who themselves are both the targets and agents of curriculum policy, and later the Registrar. For that was made reflexive interviews with eigth teachers that teach in São Paulo metropolitan region, than we could see that they adapt their external determinations in their own reality

Estudo das propriedades dinâmicas e sincronização no mapa de rede de Zaslavsky

Synchronization in nonlinear dynamical systems, especially in chaotic systems, is field of research in several areas of knowledge, such as Mechanical Engineering and Electrical Engineering, Biology, Physics, among others. In simple terms, two systems are synchronized if after a certain time, they have similar behavior or occurring at the same time. The sound and image in a film is an example of this phenomenon in our daily lives. The studies of synchronization include studies of continuous dynamic systems, governed by differential equations or studies of discrete time dynamical systems, also called maps. Maps correspond, in general, discretizations of differential equations and are widely used to model physical systems, mainly due to its ease of computational. It is enough to make iterations from given initial conditions for knowing the trajectories of system. This completion of course work based on the study of the map called ”Zaslavksy Web Map”. The Zaslavksy Web Map is a result of the combination of the movements of a particle in a constant magnetic field and a wave electrostatic propagating perpendicular to the magnetic field. Apart from interest in the particularities of this map, there was objective the deepening of concepts of nonlinear dynamics, as equilibrium points, linear stability, stability non-linear, bifurcation and chaos

Utilização de biossurfactante e surfactante químico para dessorção de óleo presente em vermiculita hidrofobizada: estudo comparativo

A number of methods and products have been developed in order to eliminate or reduce the negative effects that hydrocarbons cause to the environment, including hydrophobic expanded vermiculite, used in oil residue filtering systems at gas stations. However, upon adsorbing organic compounds, the vermiculite is no longer used and is sent to landfills. The aim of the present study was to wash granular and powdered vermiculite containing oil lubricant in its pores with distilled water and solutions of 0.1% SDS surfactant and rhamnolipids, with the aim of removing the lubricant and the possibility of reusing the mineral. The greatest amount of lubricant removal was obtained through washing with 0.1% SDS and both granulometric forms. This may be associated to the industrial purification received by the surfactant. However, the biosurfactant is ecologically more viable due to its low toxicity and ease of degradability. In the readsorption tests, greatest adsorption was obtained with the granular vermiculite washed in SDS solution. In order to enable the reuse of the mineral, further tests are needed to enhance desorption/adsorption efficiency.

Significados e expectativas de crianças das camadas populares em relação à escolarização

Nowadays, we understand the childhood as a result of historical and social changes. This work aims to comprehend representations and expectations made by children from the popular classes in the initial years of Fundamentaql Education. We conducted a research with six students from a public school that attends children from urban popular layer's families. The research examines the meanings and representations of educational practices developed in the relationships established among teachers, students and families through their life stories. Among the results, we can say that the environment of differentiation in the school id perceived to the students because they introject teacher's representations about their performance. Scientific studies show that children crystallize a positive image of the shool when the speech and posture of the institution value and encourage learning. However, the students are challenged to produce better results in order to participate in extracurricular activities, which they are excluded todue indiscipline or learning difficulties. The mean of the schooling is highly influenced by the performance of students and also by the attitude of educators in the family and in the school. The theoretical review points out that when students have a good performance, the merit is attributed to stress and ease they have to acquire the learning contents. In other hand, struggling students or with a lag of content explains the academic problems stems from the lack of capacity and potential for acquisition of learning compatible with age, defining schooling as something necessary for training, but which is inaccessible in their life stories
