As febres paulistas na Sociedade de Medicina e Cirurgia de S?o Paulo: uma controvérsia entre porta-vozes de diferentes saberes
Teixeira, Luiz Antonio;
História, Ciências, Saúde-Manguinhos , 2004, DOI: 10.1590/S0104-59702004000400003
Abstract: at the close of the nineteenth century, s?o paulo physicians were debating a disease they classified as "febres paulistas" (s?o paulo fevers). the article presents a brief overview of the role of fevers within brazilian nosology at that time and describes how science then explained febres paulistas, malaria, and typhoid fever. changes in the medical field meant febres paulistas were no longer classified as forms of malaria but instead considered cases of typhoid fever. following the society's debates surrounding this shift, the article analyzes the scientific lines that tended to identify febres paulistas with malaria or typhoid fever and also the line that believed these fevers were an independent nosological entity.

O controle do cancer no Brasil na primeira metade do século XX
Teixeira, Luiz Antonio;
História, Ciências, Saúde-Manguinhos , 2010, DOI: 10.1590/S0104-59702010000500002
Abstract: the article discusses public efforts to control cancer in brazil from the 1920s to the close of the 1940s. it examines the process which brought about creation of the inspectorship to combat leprosy, venereal diseases, and cancer within the national department of public health. creation of the inspectorship was the first public action to target cancer and, while it was not far-reaching, its emergence enables us to understand the professional field of cancer at that time. the text also points to the role played by the diffusion of electrosurgery in expanding medical interest about cancer and in the founding of the cancerology center in the federal district. it discusses the establishment and first decade of activities of the national cancer service, endeavoring to link the service's initial profile with the issues that guided its history.

História, Ciências, Saúde-Manguinhos , 1997, DOI: 10.1590/S0104-59701997000200003
Abstract: the article analyzes how gilberto freyre addresses health-related issues in his book master and slave. the first point of focus is how the sanitation movement that emerged in the sert?o region in the late 1910s influenced freyre's essay. the article next endeavors to understand the relation between freyre's emphasis on the problem of syphilis in brazil and the issues of race and miscegenation, both of which are constants in his works. lastly, the article endeavors to situate freyre's ideas within the ideological framework of eugenics that was in fashion in brazil at the time his works were written.
Cibercultura e literatura: hipertexto e as novas arquiteturas textuais
Diniz, Luiz Antonio Garcia;
Alea : Estudos Neolatinos , 2005, DOI: 10.1590/S1517-106X2005000200003
Abstract: the object of this study is to analyse the implications of the new technologies in the perceivable (reader) and technical (author) forms of textual production. cyberculture, the result of the trivialisation of personal computers and of the new relationships created by virtual communities in an environment characterised by interactivity, has imposed a new paradigm. our focus is the relationships established between literature, cyberculture and the cybercity by the newly emerging textual forms. what is the role of the book in cyberspace and in immersive environments? how would temporality be defined in the contemporary text, characterized by a growing fractality? if hypertext is characterised as something opposed to linear text, how may we define hypertext in relation to printed text, a product characterised by the notion of the author and individuality?

Rochelle, Luiz Antonio;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1976, DOI: 10.1590/S0071-12761976000100012
Abstract: this paper deals with characterization of fruits of 13 cultivars belonging to 3 species: cucurbita moschata duchesne, cucurbita maxima duchesne and cucurbita pepo linneu. it was used seeds from controlled pollination. it was considered following characteristics of fruits : epicarp, shape, weight, resistance of the bark, dimensions and thickness of pulp; for seeds were considered: number, dimensions and weight.
Contribui??o ao conhecimento do Cruá (Sicana odorifera Naud.)
Rochelle, Luiz Antonio;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1986, DOI: 10.1590/S0071-12761986000200004
Abstract: the experiment was done in order to increase the knowledge of cruá (sicana odorifera naud.) of the appreciable quality, as well to evaluate some aspects related to morphology in the initial growth. the seeds utilized in the experiment were obtained in perfect conditions and some in greenhouse of didactic vegetagle garden, botany department esalq. the seeds were arranged in two positions at sowing: horizontal and vertical. substratum utilized was mixture of forest soiland river sand. it was verified that positions of seeds do not affected germination, but to morphological characters there was significative differences. to length of future principal root (cr), length of petiole (cp) it was detected significance at 5% level, also for distance between cotyledonous leaves to insertion of definitive first leaf (dfcifd), length of limb (cl) and breadth of limb (ll) were detected significances at 1% level. these significances refered to seeds in the horizontal position. the distance between collum to insertion of cotyledonous leaves (dcifc) was not significative.
Descri??o taxon?mica de cultivares de Cucurbita Moschata duchesne
Rochelle, Luiz Antonio;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1973, DOI: 10.1590/S0071-12761973000100010
Abstract: we summed up the results of the studies of 7 cultivars belonging to specie cucurbita moschata, taking into account their botanical description because they have not been taxonomically characterized yet, though largely known and grown for their economical value. the breeding works of the cultivars of the above mentioned specie have been carried out since 1942 by the section of olericulture of agronomic institute of campinas (i. a. c.) view of the economic importance the|y have. we used seeds from controlled pollination, given away to us by the iac-olericulture section, in order to obtain the plants of the 7 cultivars. the statistical planning followed the steps of distribution at random using the 7 cultivars with 10 replications. the botanical description of the cultivars was based upon the morphological characteristics of the vegetative and floral organs and upon the characteristics of the fruits and seeds as well, taking into consideration: a - the shape, dimensions, presence of lengthwise striae and indumentum of the main stem. b - the dimensions and indumentum of the petiole, the angle formed by the outer ribs at the base of the leaf blade and the angle magnitude, the length of the ribs, the presence or absence of silvery spots on the leaf blade; width an length of leaf blade. c - the shapes of the tendrils. d - for the male and female flowers: the length of the peduncle, the length of the tube and of the lobules of the calyx and its shape, the length of the tubes and of the lobules of the corolla, the diameter of the upper part the corolla tube, diameter between the apexes of the corolla lobules, the length of the filament and the length of the anther, and the shape of the latter for male flowers; the dimensions, positionings, shape and indumentum of the ovary, length and color of stigma, length of the stigma lobules, the variable shape of the nectariferous disk at the style base for female flowers. e - the dimensions, shape, color, parts, consistence and thickn
