Sombreamento dos cafèzais II: resultados do 4.° biênio (1959/1960)

This paper deals with data obtained in 1959 and 1960 in shaded and unshaded coffee plots at Piracicaba, São Paulo, Brazil. The results can be summarized as follows: a) the production, in shaded and unshaded plots, did not show differences statisticaly significant; b) the percentage of coffee berry borer infestation was higher in shaded plots as compared with unshaded ones; c) the percentage of green, ripened and dry fruits depends of the year and of the harvest time. In the same harvest time, both for shaded and for unshaded plots the percentages in the shaded plots were higher for green fruits and lesser for ripened and dry fruits; d) coffee fruits brought from the field in the harvest time yielding up in unshaded plots as compared with shaded ones; e) the relation grains/dry fruits was better in shaded plots.

Avaliação do período de florescimento das plantas apícolas no ano de 1960, através do polem contido nos méis e dos coletados pelas abelhas (Apis Mellifera L.)

Neste trabalho apresentamos os resultados da análise polínica de 11 amostras de mel e de polem coletados pelas abelhas Apis mellifera L., durante o período de março de 1960, no Apiário da Escola Superior de Agricultura "Luiz de Queiroz". Através dessa análise, pudemos comprovar e identificar como plantas nectaríferas e poliníferas as seguintes espécies: Eucalyptus sp., Dombeya sp., Agave sisalana, Vernonia sp., Montanoa bipinnatificada, Persea americana, Baccharis sp.. Citrus sp., e como plantas poliníferas as que seguem: Bidens piíosus, Cosmus sulphureus, Pirostegia venusta, Mel-linis minutiflora. Pudemos, assim, avaliar de modo indireto o período de florescimento das plantas apícolas nos arredores do apiário da Escola e comparar essa avaliação com as observações diretas de KERR & AMARAL (196°) sobre o período de florescimentos das plantas apícolas no planalto Paulista. Daí podermos afirmar ser a análise polínica dos méis e a análise dos polens coletados pelas abelhas um método prático de valor para estudos de fenologia das plantas apícolas. Poderemos assim aplicar a análise polínica em nossos futuros estudos sobre a fenologia das plantas apícolas em diferentes regiões do Estado de São Paulo.

Sombreamento dos cafezais V: resultados de mais dois bienios: 1967/1968 - 1970/1971

Os dados obtidos durante os anos de 1967 a 1971 (2 biênios: 1967/1968 e 1670/1971) no cafèzal da E.S.A. "Luiz de Queiroz", parte sombreada e parte a pleno sol, foram estudados no presente trabalho, complementando aqueles de sete biênios já descritos em trabalhos anteriores. Os resultados obtidos, analisados estatisticamente em relação à produção, porcentagem de broca, porcentagem de frutos verdes, de maduros e de sêcos, rendimento de café da roça, relação café beneficiado/café coco e peneira média, permitiram as conclusões seguintes, principalmente em relação aos biênios estudados: a. o lote sombreado, em relação a um dos lotes não sombreado, apresentou diferenças significativas quanto à produção, em favor para o sombreado; isso se deve provavelmente ao fato de as plantas de sombra estarem agora em decadência com muitas árvores mortas, favorecendo o lote sombreado pela luz e pela matéria orgânica acumulada; b. a porcentagem de broca continuou a ser, em geral, sempre maior nos lotes sombreados; c. as porcentagens de frutos verdes, de maduros e de sêcos dependem, em geral, do ano e da época da colheita.

Publishing performances of spanish academics: 1970-2004

The aim of this note is to complement some of the results appearing in Dolado et al. (2003) article “Publishing Performance in Economics: Spanish Rankings” Particularly we want to focus on three issues: the robustness of the results regardless of the time span considered, the evaluation of a researcher to the advance of the knowledge, and to what extent the choice of a particular database to download the results can affect the results. Differences are significant when we expand the time period considered. There are also small but significant differences if we combine datasets to derive the rankings.

Publishing performance of spanish academics: 1970-2004: institutions, researchers et al.

This work complements some of the results appearing in the article ?Publishing Performance in Economics: Spanish Rankings? by Dolado et al. . Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments versus institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered.

Poliomyelitis: epidemiological aspects in Rio de Janeiro (Guanabara State) and adjacent areas in the period from 1961 to 1970

Based on the available data from the Hospital responsible for the care of paralitic poliomyelitis cases in Rio de Janeiro City (Guanabara State) and adjacent areas, and the laboratory studies carried out on these patients, the authors analize epidemiological aspects of poliomyelitis in a period of ten years (1961 to 1970). Paralitic poliomyelitis remains a public health problem, with a typical incidence in the less than 4 year age group. All three poliovirus types have been prevalent for at least one period of time during the last ten years. Trivalent oral vaccine has been used since 1961 but the vaccination levels achieved were not enough to a permanent control of the disease. A definite seasonal distribution of cases could not be observed with the available data. Active mass campaign vaccinations with previous motivation of all segments of the population, specially the low-income groups instead of passive waiting of children in Vaccination Centers seems to be the best aproach to control poliomyelitis in this area.

Material flow accounting of Mexico (1970-2003)

This technical background paper describes the methods applied and data sources used in the compilation of the 1980-2003 data set for material flow accounts of the Mexican economy and presents the data set. It is organised in four parts: the first part gives an overview of the Material Flow Accounting (MFA) methodology. The second part presents the main material flows of the Mexican economy including biomass, fossil fuels, metal ores, industrial minerals and, construction minerals. The aim of this part is to explain the procedures and methods followed, the data sources used as well as providing a brief evaluation of the quality and reliability of the information used and the accounts established. Finally, some conclusions will be provided.

The life history of Hepatozoon leptodactyli (Lesage, 1908) Pessoa, 1970: a parasite of the common laboratory animal: the frog of the genus Leptodactylus

The main object of the present paper is to furnish a brief account to the knowledgement of Protozoa parasitic in common Brazilian frog of the genus Leptodactylus for general students in Zoology and for investigators that use this frog as a laboratory animal. Hepatozoon leptodactyli (Haemogregarina leptodactyli) was found in two species of frogs - Leptodactylus ocellatus and L. pentadactylus - in which develop schizogony whereas sporogony occurs in the leech Haementeria lutzi as was obtainded in experimental conditions. Intracellular forms have been found in peripheral circulation, chiefly in erythrocytes, but we have found them in leukocytes too. Tissue stages were found in frog, liver, lungs, spleen, gut, brain and heart. The occurence of hemogregarine in the Central Nervous System was recorded by Costa & al,(13) and Ball (2). Some cytochemical methods were employed in attempt to differentiate gametocytes from trophozoites in the peripheral blood and to characterize the cystic membrane as well. The speorogonic cycle was developed in only one specie of leech. A brief description of the parasite is given.

Isolamento e caracterização de Pseudomonas maltophilia (Hugh & Ryschenkow, 1960) de material clínico humano, na cidade do Rio de Janeiro

Os autores estudaram as propriedades morfo-bioquímicas e a sensibilidade às substâncias antimicrobianas, de uma nova e rara espécie de Pseudomonas, a Pseudomonas maltophilia (Hugh & Ryschenkow, 1960), isolada de secração vaginal. Como características marcantes, dentre mais de 65 testadas, as amostras estudadas mostraram ser: oxidase negativa e lisina descarboxilase positiva; produziram desoxiribonuclease e um pigmento escuro que se difunde no meio; atacaram oxidativamente a maltose tanto em meio complexo nitrogenado como em meio de Hugh & Leifson e hidrolisaram a esculina. As amostras foram sensíveis ao cloranfenicol, gentamicina, kanamicina, colistin e gabromicina.

Bactérias Gram-negativas com fator infeccioso de resistência a drogas, isoladas de crianças em dois hospitais do Rio de Janeiro

Enterobactérias com fator infeccioso de resistência a drogas, foram isoladas em fezes de 113 crianças internadas no Instituto de Puericultura da U.F.R.J e no Hospital Jesus nos períodos 1960-1964 e 1970-1973, verificando-se que 71,6% das crianças excretaram bactérias resistentes, das quais 41,3% a uma única droga e 58,7% a várias drogas.

Morbidade da esquistossomose mansoni no Brasil. I - Estudo de 4.652 casos observados no Rio de Janeiro de 1960 a 1979

No período de vinte anos (1960-1979), os autores observaram na Clínica de Doenças Infecciosas e Parasitárias da Faculdade de Medicina da Universidade Federal do Rio de Janeiro, sediada no Pavilhão Carlos Chagas do Hospital São Francisco de Assis, 4.652 casos de esquistossomose mansoni procedentes de 18 Estados do Brasil. Entre os casos observados 87,18% eram da forma hepatointestinal e 12,82% da forma hepatoesplênica entre os quais 30 tinham a forma pulmonar associada. Adicionalmente 30 casos da forma aguda ou toxémica foram estudados no mesmo Serviço, em famílias residentes no Rio de Janeiro. Além da observação clínica e do estudo epidemiológico incluindo o perfil migratório de cada caso e da casuística como um todo, foram realizados exames complementares como hemograma, mielograma, dosagem de transaminases, provas de função hepática, eletroforese de proteínas séricas, biópsia hepática, radiografias de tórax e de esôfago, esplenoportografia, eletrocardiograma e estudos hemodinâmicos do sistema porta, do coração e da artéria pulmonar em grupos de pacientes selecionados.
