Abstract: testing the tractor in agricultural soil is one way of getting information, particularly with regard to the development of traction. the yield at the drawbar is often used to compare or evaluate tractors. however, drawbar performance is affected by the conditions of the displacement surface, the gear ratio and the ratio between the weight and power of the tractor. the objective of this study was to evaluate the yield at the drawbar of a tractor at different weight to power ratios, with different loads on the drawbar. the test was conducted at the lageado experimental farm ,belonging to unesp, on botucatu campus in s?opaulo, by evaluating the following weight to power ratios: 50, 55 and 60 n kw-1, where for each of these ratios, three intervals of force on the drawbar were used, as follows: 15 to 20, 25 to 30 and 35 to 40 kn. it was concluded that the weight to power ratios and the loads studied showed little variability. the weight to power ratios of 50 and 55 n kw-1, for loads on the drawbar of 25 to 30 and 35 to 40 kn, showed differences between their averages, with the highest yield at the drawbar being obtained for a load of 25 to 30 kn, where the average was 50.9 and 54.1% respectively. as for the weight to power ratio of 60-n kw-1, there was no difference in the averages for loads of 25 to 30 and 35 to 40 kn.

Abstract: Currently great emphasis is given for seed metering that assist rigorous demands in relation to longitudinal distribution of seeds, as well as to the index of fails in spacing laws, breaks and double seeds. The evaluation of these variable demands much time and work of attainment of data and processing. The objective of this work went propose to use of graphs of normal probability, facilitating the treatment of the data and decreasing the time of processing. The evaluation methodology consists in the counting of broken seeds, fail spacing and double seeds through the measure of the spacing among seeds, preliminary experiments through combinations of treatments had been carried through whose factors of variation were the level of the reservoir of seeds, the leveling of the seed metering, the speed of displacement and dosage of seeds. The evaluation was carried through in two parts, first through preliminary experiments for elaboration of the graphs of normal probability and later in experiments with bigger sampling for evaluation of the influence of the factors most important. It was done the evaluation of seed metering of rotating internal ring, and the amount of necessary data for the evaluation was very decreased through of the graphs of normal probability that facilitated to prioritize only the significant factors. The dosage of seeds was factor that more important because factor (D) have greater significance. Atualmente grande ênfase é dada para mecanismos dosadores de sementes, que devem atender exigências cada vez maiores em rela o à qualidade de distribui o longitudinal, principalmente em rela o ao índice de falhas, quebras e duplas. A avalia o destas variáveis demanda muito tempo e trabalho, tanto para obten o de dados como para processamento. O objetivo deste trabalho foi propor a utiliza o de gráficos de probabilidade normal para facilitar o tratamento dos dados relativos aos fatores que possivelmente influem na qualidade de distribui o e diminuir o tempo de processamento dos dados de distribui o das sementes em semeadoras. A metodologia de avalia o constitui-se na medida dos espa amentos entre sementes e contagem de sementes quebradas, espa amentos falhos e sementes duplas. Foram realizados experimentos por meio de combina es de tratamentos cujos fatores de varia o foram: o nível de sementes no reservatório, o nivelamento transversal da semeadora, a velocidade de deslocamento e a dosagem de sementes. Uma avalia o de semeadora provida de anel interno rotativo foi realizada em duas partes primeiramente com experimentos para constru

Abstract: in the twentieth century, women with leprosy could not carry on their maternity because of the statement of compulsory isolation of patients, adopted to control the disease. their children were taken at birth to prevention centers and the contact of mothers with their babies was only visual. in order to understand the experience of maternity in the leprosaria it was carried out an investigated narrative research with three mothers who lived through the period of compulsory internment. the speeches reveal two distinct moments in the experience of motherhood: the separation of the children with their subsequent return to home and the adoption of other children to achieve motherhood. it is considered that the adoption has promoted the meeting with the meaning of existence that had been broken and allowed the experience of being a parent.

Fractal : Revista de Psicologia , 2008, DOI: 10.1590/S1984-02922008000200021
Abstract: we analyze the capture of the literary object made by culture and by specialized critical. we pointed the interpretation and the systematization is a reactionary way of use of literature, helping to restrict the freedom excited for literary experience. we conclude that, the institutional culture unifies and fits the literary compositions, the commerce presents a pasteurizer role of the literary trespass and a part of literary critique unpowered the workmanship. but we thought that exist many critique ways that run away to this unpowerment character of the workmanship, making that to be what it is: an intense space of experimentation.
A fun??o-autor: examinando o papel do nome do autor na trama discursiva
Almeida, Leonardo Pinto de;
Fractal : Revista de Psicologia , 2008, DOI: 10.1590/S1984-02922008000100021
Abstract: from the foucault, brunn and chartier's thoughts, we analyze the emergency of the modern author. in relation to history, foucault shows as the authorial figure was invented through a tram of events that goes of the responsabilization of the discourse's agent to the function of reference. he indicates the characteristics of the name of the author, designating that it has for function to delimit, to classify and to organize the universe of the discourses. this name is one of the functional principles that conduct our relation with knowing and with literature on behalf of a power and of an authority.

Reflex?es sobre a experiência moderna e a liberdade
Almeida, Leonardo Pinto de;
Fractal : Revista de Psicologia , 2010, DOI: 10.1590/S1984-02922010000900011
Abstract: this paper aims to analyze the relation between the advent of the modern experience and the question of freedom, from a reflection on the event of the death of god. following the reflections contained in the workmanships of foucault, sartre, sloterdjik, blanchot, we examined the specificity of the nietzschean′s thought of the death of god and its consequences for the life and the modern experience. thus, we concluded that the modern experience would point out a paradox that designates a movement that would be between the freedom as continuous task and the shades of gods who obliterate the field of experimentation and the exercise of the freedom
