Hemispheric strokes: clinical or surgical management? Intracranial pressure monitoring of a case and review of the literature
Carvalho, Gustavo Adolpho;Carvalho Filho, Adolpho;
Arquivos de Neuro-Psiquiatria , 1995, DOI: 10.1590/S0004-282X1995000500020
Abstract: the authors report a case of a right hemispheric ischemic infarction on a 77-year-old patient that was monitored with an extradural intracranial pressure monitor (ladd device).we show the huge intracranial hypertension that the brain was submitted despite of the medical treatment. the treatment of hemispheric strokes can be very challenging. the usual antiedema drugs very often prove to be of no help against the mass effect and the high intracranial pressure that some patients present. more recently reports on the literature are showing good results following a decompressive surgery on such ischemic infarcts.
Reforma agrária: de elei??es a elei??es
Carvalho Filho, José Juliano de;
Estudos Avan?ados , 1997, DOI: 10.1590/S0103-40141997000300006
Abstract: this article, taking advantage of the presidential election nearness, presents two reports: the first one recollects the treatment given to the land property issue during the past presidential electing period, and the second examines the accomplishment of the land policy of the fernando henrique cardoso's government, opposing to the social movements' struggle. the general conclusion is that the governmental initiatives have essentially been provoked by the aggravation of the land conflicts and by the attitudes of the social movements, in special the mst (peasants' movement), weighty nevertheless with the land property policy conservative attitude. aspiring the next election contest, the government shows some initiatives towards the land property reform, trying nevertheless to disqualify the social movements' struggle.
Impunidade no Brasil: Col?nia e Império
Carvalho Filho, Luís Francisco;
Estudos Avan?ados , 2004, DOI: 10.1590/S0103-40142004000200011
Abstract: impunity is at the core of the brazilian political debate. a retrospective look at legal documents and accounts by historians, travelers and chroniclers for references to the application of the death penalty for common crimes (as opposed to political, military and religious offenses) shows that impunity has always been the order of the day in the history of brazil. despite the repressive violence, evident at several moments, a constant feature of both colonial and imperial periods was the ineffectiveness of the penal law as it was written, made so either by the granting of pardons, the lack of political will or by practical impediments.
Scent-robbing and fighting among male orchid bees, Eulaema (Apeulaema) nigrita Lepeletier, 1841 (Hymenoptera: Apidae: Euglossini)
Carvalho Filho, Fernando da Silva;
Biota Neotropica , 2010, DOI: 10.1590/S1676-06032010000200038
Abstract: male neotropical orchid bees (euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. the ultimate causes of euglossine fragrance collection remain a mystery. recent evidence suggests that odoriferous substances play a role in euglossine courtship and serve as indicator of male genetic quality. males of eulaema nigrita were observed robbing scents from the detached hind legs of a conspecific male e. nigrita in belém, brazil. the hind leg seemed to have been detached during fights between males, since one male was missing a hind leg where the observation was made. this behavior appears to be common among males of e. nigrita since more than one case was observed on the same day. the observation reported here shows that males of e. nigrita with tibiae filled with fragrances are attacked by conspecific males that attempt to steal it.
Melhoramento do cafeeiro: XI - Análise da produ??o de progênies e híbridos de bourbon vermelho
Antunes Filho, H.;Carvalho, Alcides;
Bragantia , 1957, DOI: 10.1590/S0006-87051957000100013
Abstract: during the initial years of a breeding project carried out in campinas, coffee progenies and hybrids were usually planted in rows of twenty plants each. progenies were not replicated in the same location but usually they were studied at three to five experiment stations. although this method did not allow for statistical analysis of individual yields and other plant and seed characteristics, it proved to be sufficiently accurate to select several outstanding progenies and exceptional individual coffee plants. individual yields of 856 plants belonging to forty-three of such groups of twenty plants each were studied in order to evaluate the effect of an early elimination of progenies which started yielding below the general mean. the 43 groups were derived from 25 bourbon plants, 24 groups being selfed progenies and 19 f1 hybrids between a few of those trees. in a previous paper it was shown that these progenies and hybrids did not differ in yielding ability, thus allowing treatment as a single population of bourbon plants. individual harvests of each plant from this population were recorded during the first six years of yields (1939-44). a preliminary selection was done in 1944. the five progenies and five hybrids which had the highest mean yields were selected as groups of twenty plants and continued under observation for an additional period of eight years. besides these 200 coffee trees, 139 others were also selected for their high individual yields during the first six years of crop, and their records were also kept for another period of eight years, ending in 1952. the remaining trees were not recorded after the preliminary selection. average yields per plant were calculated for the 43 groups, accumulating the crops of the first 2, 4 and 6 years, and distributed, for each period, in classes centered at the general mean plus or minus integer multiples of the corresponding standard error. in the distribution for the first two years of crop (1939-40), 10 groups wer
Melhoramento do cafeeiro: XII - Variabilidade em linhas puras de café

Abstract: three isogenic progenies of red bourbon coffee (coffea arabica l.var. bourbon (b. rodr.) choussy) were investigated in relation to several characteristics in a balanced lattice experiment with 16 entries, five replications, each plot with four individual plants. two of these isogenic progenies were obtained by artificial self-pollination of two plants which were derived from haploid sporophytes after their chromosomes were duplicated (357-21 and rp 13). the third isogenic progeny is the f1 of the hybrid between those duplicated plants (h 1934). among the remaining 13 entries of this trial more attention was given to the following progenies of red bourbon coffee: 959, s0 from open pollinated seeds taken in a private farm; 43-18-11, selfed s3 from a selected plant; 43-7-7-15 and 43-7-19-13, selfed s4 progenies of similar pedigrees. plant height was measured for all entries five years after transplantation to the field. it was observed that the f1 did not show heterosis for this characteristic, its average height being intermediate between those of the two isogenic progenies. the within plot variance presented by the f1 is equal to that of one of the pure lines and close to that of the other. the average height presented by the s3 and the s4 progenies originally derived from plant c 43 suggests that successive selfing does not reduce plant height (table 3). total yields in kilograms of riped fruits of individual plants were recorded for the first three years of crops. the mean yield of the f1 is higher than those of the two isogenic lines, although this difference is not significant. the within plot variance of yields is smaller for the f1 than for the two pure lines, but again the differences are not significant. when separate analyses were made for the annual crops of the three isogenic progenies, it was seen that the smallest within plot variance was presented by the f1 in two of the three years. the within plot variances for the total yields of the s3 and s4 progen
Melhoramento do cafeeiro: X - Sele??o visando eliminar o defeito "lojas vazias do fruto" no café Mundo Novo
Carvalho, A.;Antunes Filho, H.;
Bragantia , 1955, DOI: 10.1590/S0006-87051955000100006
Abstract: a high proportion of plants of the mundo novo coffee (a strain of coffea arabica l. var. bourbon (b. rodr.) choussy) produce an abnormally large number of fruits with empty locules. since this character reduces the rate of coffee beans per weight of fruit, selection was started aiming at reducing or eliminating plants having this defect, and thereby increasing the yeild of coffee beans. preliminary investigations carried out in 1950 on the occurrence of empty locules in selfed progenies and hybrids of the bourbon plant no. 44, which presents a high percentage of this defect, indicated that this characteristic was heritable. it was also determined that only normal plants were found in progenies of normal individuals, even when these belonged to progenies in which some of the sibs produced large number of fruits with empty locules. based on this information, seeds from normal, high yielding plants of mundo novo coffee were released to coffee growers in 1950. in one of the first farms to use selected seeds of mundo novo coffee, approximately 7,000 trees (one tree is really a group of four plants in the same hill) were planted with seeds produced by the best plants of five of the most outstanding progenies of this variety. a small crop was available in 1953. due to the increasing demand for selected seeds of mundo novo coffee, it was then suggested that the state extension service buy the seeds produced in this farm and distribute them to coffee growers that were willing to plant them for seed production. before this suggestion was put into effect, the whole planting was surveyed for the presence of plants producing large numbers of fruits with empty locules. by means of a sampling technique, it was determined that only from 2 to 7 per cent of abnormal plants were found in the plantation. when these numbers were contrasted with the 50 per cent index of undesirable trees normally found in the original mundo novo plantings, it became evident that selection to eliminate pl

Abstract: vegetative propagation of coffee plant by means of graft or cuttings has frequently shown that the bud which develops into plagiotropic branches is so differentiated that it looses the capacity to produce upright growing branches (orthotr?pic). two independent cases found by a. j. t. mendes and j. e. t. mendes are described in this paper, of a plagiotropic branch from which an oithotropic branch has developed, indicating that in very rare cases the differentation of the plagiotropic branch is not so complete. another case is also described of an orthotropic branch that up to the present time sems to have changed into a plagiotropic one.
