Plants that deploy a phosphorus (P)-mobilising strategy based on the release of carboxylates tend to have high leaf manganese concentrations ([Mn]). This occurs because the carboxylates mobilise not only soil inorganic and organic P, but also a range of micronutrients, including Mn. Concentrations of most other micronutrients increase to a small extent, but Mn accumulates to significant levels, even when plants grow in soil with low concentrations of exchangeable Mn availability. Here, we propose that leaf [Mn] can be used to select for genotypes that are more efficient at acquiring P when soil P availability is low. Likewise, leaf [Mn] can be used to screen for belowground functional traits related to nutrient-acquisition strategies among species in low-P habitats.

Enfatiza-se a importância da realidade e da experiência atual na constituição do sujeito, por meio da apresentação das ideias de Hans W. Loewald e do exame de sua concepção original de realidade. A natureza relacional das pulsões, a ideia do novo objeto na relação analítica, a noção de invenção da realidade, o conceito de sublimação e a forma de compreender o simbolismo estão entre as formulações mais importantes de Loewald acerca do papel do ambiente na constituição do sujeito. Suas formulações também permitem a compreensão da inserção do sujeito na realidade social contemporânea.

As the foundation of the University of São Paulo completes 75 years, this article describes the history of a mansion at 463 Glette Boulevard, in São Paulo city, where several undergraduate courses of the University's Philosophy, Sciences and Letters Faculty operated until 1969. The first building of the school of Chemistry was erected there, 70 years ago. A brief retrospective of the Department of Chemistry at that place is given. The mansion was torn down by the middle of the 1970s, but it remained as a symbol of the school identity in the memory of all those who studied there.

Only a few decades after 1492, when Christopher Columbus arrived on a Caribbean island and Pedro Alvares Cabral claimed Brazil for Portugal in 1500, a German mercenary gave the first description of stingless bees in 1557. He got to know them when he was imprisoned for months by an anthropophagous tribe in the coastal region of Santos, today in the State of Sao Paulo. This rather short but nevertheless extremely exact record on stingless bees is hidden in the first book on Brazil. Three species and important aspects of their life history were treated. This early description has been completely overlooked by bee scientists until now. My note intends to close this evident gap.

O presente trabalho objetiva estimar o número de professôres, prédios escolares e vagas no curso primário, necessários para o atendimento da população que a êle irá se dirigir, no Estado de São Paulo. Baseadas em tábuas de sobreviªncia, foram feitas projeções populacionais até 1980, em períodos qüinqüenais, a partir de 1950. Atra©s de algumas hipóteses concernentes às taxas de matrículas esperadas até aquela data, estimou-se o número de crianças que estarão matriculadas e as necessidades para seu atendimento.

Foi feito estudo visando a determinação das taxas de medida da doença meningocócica em japoneses e seus descendentes, do município de Londrina, Paraná, Brasil. A morbidade por doença meningocócica (DM) foi cerca de 7 meses mais baixa que no restante da população, tendo sido nula entre os mesmos a ocorrência de óbitos, tanto em fase endêmica, como epidêmica, A revisão dos prontuários médicos hospitalares correspondentes aos casos notificados exclui o diagnóstico de DM em 75% dos pacientes de origem japonesa e em 20% da amostra de pacientes não japoneses. É discutida a eventual relação de fatores sócio-econômicos e cultural (alimentar) às observações.

Brazil's nosologic profile has been sustaining profound modifications. Some occurred because of massive immunization campaigns and socioeconomic and demographic trends. Some yet were pure nosologic transitions, such as the emergence of AIDS. In this demand study it is described how these changes reflected on the 8,630 admissions of an Infectious Diseases Department in Niterói, along a thirty year period. Brazilian rural endemic diseases were infrequent (3.45%). Men predominated (62%) all the time, in all age strata and in nearly all diseases. Children under fifteen predominated until 1983. There was, in the case of tetanus, a striking rise in age strata. Institutional mortality dropped from 31% in 1965 to 10% in 1984, but rose since then to 15% in 1994. However, if AIDS patients had not been computed, mortality would have kept descending till 8% at the end of the study period. The crescent unimportance of immunopreventable diseases paralleled with the growing prominence of AIDS. In less than a decade, AIDS ranked fifth among the most frequent diseases in the whole period of thirty years. As opposed to the immunopreventable diseases, neither meningitides nor pneumonia appear to be in decline. AIDS, by its exponential incidence, by its chronic character, and by the uncountable opportunistic infections it determines, imposes itself as a challenge for the coming years.

In the present work the life cycle of Psammolestes tertius was studied. The mean length, in days, fromeach stage was: 26.3 (± 1.7) (1st), 28.6 (± 1.8) (2nd), 28.4 (± 1.8) (3rd), 32.2 (± 1.9) (4th) and 33.5 (± 5.8) (5th). The mean egg incubation period was 15.7 days (± 1.7). Overall mortality was 48.9% and egg viability was 65.7%.
