Sobre um retrato vivo de Kleist
Pompeu, Douglas;
Pandaemonium Germanicum , 2011, DOI: 10.1590/S1982-88372011000200004
Abstract: the purpose of this paper is to present a discussion of some of the main characteristics of robert walser's short story kleist in thun, in an attempt to reflect on how the literary text can establish a dialogue with tradition. this is achieved by the fictionalisation of the character of a real author, more specifically by the narrative genre often used by walser: the portrayal.

Abstract:
Effects of caffeine on the electrophysiological, cognitive and motor responses of the central nervous system
Deslandes, A.C.;Veiga, H.;Cagy, M.;Piedade, R.;Pompeu, F.;Ribeiro, P.;
Brazilian Journal of Medical and Biological Research , 2005, DOI: 10.1590/S0100-879X2005000700011
Abstract: caffeine is the most consumed psychoactive substance in the world. the effects of caffeine have been studied using cognitive and motor measures, quantitative electroencephalography (qeeg) and event-related potentials. however, these methods are not usually employed in combination, a fact that impairs the interpretation of the results. the objective of the present study was to analyze changes in electrophysiological, cognitive and motor variables with the ingestion of caffeine, and to relate central to peripheral responses. for this purpose we recorded event-related potentials and eyes-closed, resting eeg, applied the stroop test, and measured reaction time. fifteen volunteers took caffeine (400 mg) or placebo in a randomized, crossover, double-blind design. a significant reduction of alpha absolute power over the entire scalp and of p300 latency at the fz electrode were observed after caffeine ingestion. these results are consistent with a stimulatory effect of caffeine, although there was no change in the attention (stroop) test or in reaction time. the qeeg seems to be the most sensitive index of the changes produced by caffeine in the central nervous system since it proved to be capable of detecting changes that were not evident in the tests of cognitive or motor performance.

Abstract: aiming at the knowledge of the yielding capacity of new peanut lines, 36 trials in randomized complete-block design, using 'tatu' as control were carried out in the main experimental station of campinas, during the rainy season of 1977, 1978 and 1979. the peanut lines originated from individual selection in the crosses of tatuí x roxo 80-1, tatu x introduction, tatu x tatuí, tatu x tatu amarelo, tatu x roxo 47, tatu x roxo 80-1, tatu x (tatuí x arachis monticola), tatu x (tatuí x a. villosa) and (tatu x roxo 80-1) x (tatuí x a. monticola). the statistical analyses showed that 22 lines with means of 4,219 to 6,445 kg/ha were superior to those observed for tatu, which ranged from 3,466 to 4,887 kg/ha. in thirteen analyses the effects of year and treatment x year were significant in eleven and three of them, respectively. the best lines will be included in the regional trials and seeds of some of them increased in large quantities for releasing to the growers.

Abstract: with the objective of knowing the yielding ability of dry bean lines of preto, diversos and chumbinho groups resistant to the anthracnose agent, trials in randomized complete-block design were carried out in the main experimental station of campinas in the rainy season of 1977, 1978 and 1979. 'carioca', 'moruna' and 'aroana' were used as controls for lines of diversos, preto and chumbinho groups, respectively. the results showed that the lines 5-9-4-3-1-4, 5-9-4-3-1-5, 18-1-6 and 5-9-4-3-1-6, with mean yields of 2,100, 2,079, 2,055 and 2,028 kg/ha were superior to the control moruna, which yielded 1,580 kg/ha, at 5% level. none of chumbinho lines outyielded aroana although high mean yield was obtained by 5-1-1-5-1-9 with 2,336 kg/ha compared with 2,136 kg/ha got by the control. on the other hand, the lines 10-3-1 and 10-6-2 with means of 3,133 and 2,823 kg/ha outyielded carioca which obtained 2,375 and 2,355 kg/ha, respectively. the effect of year was significant in 11 out of the 12 groups of experiments while the interaction treatment x year was observed in two of them. the best lines will be included in the regional trials and seeds of some of them increased in large quantities for releasing to the growers of campinas region.

Bragantia , 1980, DOI: 10.1590/S0006-87051980000100011
Abstract: aiming at the knowledge of yielding capacity of dry bean lines resistant to the anthracnose agent and belonging to the rosinha and roxinho groups, sixteen trials in randomized complete-block design were carried out in the main experimental station of campinas in the rainy season of 1977 and 1978, having 'rosinha g2' and 'roxo-minas' as controls. none of the rosinha lines outyielded 'rosinha g2', at the 5% level although high mean yields, around 1,830kg/ha, were observed for some of them in the pathogen absence. on the other hand, 8 lines of 'roxinho' group were superior to the control 'roxo-minas' at the 5% level having mean yields ranging from 1,490 to 2,027 kg/ha, without the presence of the pathogen. the interaction line x year was not significant but the year effect was. the best lines will be included in the regional trials and seeds of some of them increased in large quantities for releasing to the growers of campinas region.

Pompeu, Antonio Sidney;
Bragantia , 1983, DOI: 10.1590/S0006-87051983000100026
Abstract: artificial crosses were made between a. hypogaea, using lines of 'tatu', 'roxo', tatuí x roxo 80-1 and the cultivar tatuí as female parents and introduced plants of items 30001 and 30005 reported as belonging to a. diogoi and of 30006 and 30035 of a. spp, under greenhouse conditions. from the pollinated flowers of a. hypogaea x a. diogoi, 53.4 and 45.2% gave rise to pegs and fruits with normal seeds, respectively. the amount of viable pollen grains ranged from 4.8 to 13.4 with an average of 8.3% in this cross compared to 97.2 and 95.7% observed for a. hypogaea and a. diogoi. in the crosses a. hypogaea x a. sp. 30006 and a. hypogaea x a. sp. 30035, 13 and 9 normal fruits with 22 and 15 viable seeds were obtained, respectively. the pollen viability varied from 3.5 to 15 with mean of 10% in the former cross and was around 9.9% in the latter, compared with 97.8 and 98.2% noted for a. sp. 30006 and for a. sp. 30035. these results showed that plants previously classified as a. diogoi belong to another species. they also demonstrated the possibilities of using a. diogoi, a. sp. 30006 and a. sp. 30035 in the peanut genetic improvement.
Poliniza??o cruzada natural no feijoeiro
Pompeu, Antonio Sidney;
Bragantia , 1963, DOI: 10.1590/S0006-87051963000100005
Abstract: the results of two trials established to study the rate of natural cross pollination in beans (phaseolus vulgaris l.), in two different growing seasons in campinas are here discussed. two cultivares were chosen one having white flowera ('chumbinho opaco') and tlie other homozygous for the dominant allele for violet flowera ('mulatinho 1-208'). two different designs were used but in both enses only the seeds of the white flowered plants were collected and the hybrids identified after sowing in the grenhouse. in the first trial planted in the dry period (february 1959) 10 lines of the white flowered ('chumbmho opaco') were interplanted with 'mulatinho 1.208'. it was observed that 12 out 1898 plants had violet flowers, which indicated a rate of cross fertilization of 1.26%. for the trial established in the raining season (september 1961) the white flowered cultivar was planted in the center of a hexagon and in its vértices it was sown seeds of the violet flowered cultivar ('mulatinho 1-208'). the classification of the seedlings obtained from seeds of 'chumbinho opaco', indicated that 9 out 677 plants had violet flowers (1.33%). it was noticed a perfect correlation between the flower color and the pigmentation of the cotyledon. this fact will simplify the classification since the hybrids can be identified at seedling stage. although the rate of natural cross pollination, in campinas, is relatively low, it is sufficient to permit some crossing between individuals of the same population, increasing slightly the genetic variability. the cultivara isofted obtoined from individuals in the fields and selected by the pedigree method may have appeared as result of such sporadic crossings. it also suggests that in the seed multiplication plots the cultivars should be planted isolated or with borders to avoid possible contamination by natural crossings.
