Parasitizing behavior of Cervellus piranga Penteado-Dias (Hymenoptera, Braconidae, Braconinae) on papaya borer weevil Pseudopiazurus obesus Marshall (Coleoptera, Curculionidae)

Parasitizing behavior of Cervellus piranga Penteado-Dias (Hymenoptera, Braconidae, Braconinae) on papaya borer weevil Pseudopiazurus obesus Marshall (Coleoptera, Curculionidae). The papaya borer weevil Pseudopiazurus obesus is a pest associated with papaya crops in Brazil and Cervellus piranga is a naturally-occurring parasitoid which may contribute to regulate populations of this pest. We aimed at describing the parasitizing behavior of the parasitoid C. piranga on papaya borer weevil P. obesus larvae under field conditions. The sequence of events related to the parasitizing behavior of C. piranga is similar to other braconid species and includes the location and recognition of the attacked host plant followed by walks on the host plant and touching it with the tip of the antennae and the ovipositor. In the following event, the parasitoid assesses the suitability of the host by speeding up antennae and ovipositor movements. After locating and accepting the host, the parasitoid remains inactive on oviposition aperture sites and starts moving the antennae. Afterwards, the parasitoid inserts its ovipositor and starts cleaning it repeatedly. The female of C. piranga inserts the ovipositor through the hole and lay one egg into the papaya weevil borer. After oviposition, the female cleans continuously both ovipositor and antennae before leaving to forage for a new host.

Effect of Density on Marshall Stability of Hot-Mix Asphaltic Concrete, MLR-82-01, 1982

The Iowa D.O.T. specifications do not require 100 percent of 50 blow Marshall density (generally 94%) for field compaction. However, stabilities are determined in the Laboratory on specimens compacted to 100 percent of Marshall density. The purpose of this study is to determine the stabilities of specimens compacted to various densities which are below 100 percent of the 50 blow Marshall density.

Effect of Oven Heating Time of Asphaltic Concrete on Marshall Stability, MLR-82-02, 1982

It has been observed in the Laboratory that an increase in oven heating time of relatively short duration between mixing and compaction of asphaltic concrete hot mixes can have an effect on the Marshall stability results obtained. The purpose of this short investigation is to determine the effect of oven heating time on the density and stability of hot mixes.

Effect of Delay in Testing Asphalt Concrete Specimens for Marshall Stability, MLR-86-08, Draft, 1986

The Central Laboratory has been delaying the mix design testing of 2 1/2" X 4" Marshall specimens for stability, until the next day after molding. For example, if the mixes are made and samples molded on Friday a man would have to come in and work on Saturday to test these specimens. The reason for this is that the ASTM-01559 "Resistance to Plastic Flow of Bituminous Mixes Using Marshall Apparatus," states that "the specimens after being molded shall be carefully transferred to a smooth, flat surface and allowed to stand overnight at room temperature, before being weighed, measured and tested." The AASHTO procedure, AASHTO Designation T-245-82 "Resistance to Plastic Flow of Bituminous Mixtures using Marshall Apparatus," does not say when the specimens shall be tested for stability. The IDOT Lab. Specifications, Test Method No. Iowa 502-8 and test method No. Iowa 506-C "compacting asphaltic concrete by the Marshall Method" and "Resistance to Plastic Flow of Bituminous Mixtures Using the Marshall Apparatus," respectively, only state that the specimens shall be cooled before testing. Due to the above conflict in specifications, a number of mix samples were tested, in the Central Lab, for stability on different days. This should furnish enough information to allow us to change the procedure and to test for stability the same day molded, or be able to delay the testing for 3 days or more.

Aspectos biológicos e técnica de criação do gorgulho-da-goiaba, Conotrachelus psidii marshall (Coleoptera: Curculionidae)

Considerada praga-chave da cultura da goiaba, Conotrachelus psidii Marshall (Coleoptera: Curculionidae) tem causado grandes prejuízos em vários países produtores desta fruta. A pesquisa objetivou avaliar os parâmetros biológicos da praga, sob condições controladas, através do desenvolvimento de uma técnica de criação que permitiu efetuar observações diárias de pré-pupas e pupas. Constatou-se que o substrato adequado para manutenção dessas fases foi o solo argiloso umedecido com viabilidade de 78%, sendo este o tipo de solo utilizado na técnica de criação, que foi desenvolvida para trabalhos em câmara climatizada, à temperatura constante de 25 ± 1º C, fotoperíodo de 12 horas e UR de 70% ± 10%. Quanto aos aspectos biológicos, a duração média do período de ovo, larva, pré-pupa, pupa e ovo-pupa foi de: 4,25; 12,2; 106,6; 14,88 e 138,4 dias, respectivamente. A duração média do período da fase adulta, no solo, início da alimentação, pré-oviposição, longevidade e pós-oviposição foi de, 22; 11; 51,9; 149,32 e 7,18 dias, respectivamente. O período médio de oviposição foi de 120,27 dias, com um número médio de 343,63 ovos por fêmea. A técnica de criação desenvolvida permitiu acompanhar diariamente o desenvolvimento de pré-pupas, pupas e adultos do gorgulho-da-goiaba, sem que eles necessitassem reconstruir nova câmara, mostrando ser menos estressante e onerosa do ponto de vista energético.

Severity assessment of acute pancreatitis: applying Marshall scoring system

Objective: To analyze the effectiveness of the Marshall scoring system to evaluate the severity of acute pancreatitis (AP). Methods : We performed a prospective, observational study in 39 patients with AP evaluated by the Marshall scoring system and the Ranson criteria (admission and 48 hours). We assessed the progression of the disease for seven days and compared the data of the two criteria. Results : Seven patients died during the observation period and one died afterwards. All deaths had shown failure of at least one system by the Marshall method. Conclusion : The Marshall scoring system may be used as an effective and simplified application method to assess the severity of acute pancreatitis.

Modificações topográficas da junção uretrovesical e da uretra proximal após cirurgia combinada de Marshall-Marchetti-Krantz e Burch

OBJETIVO: estudar, por meio da ultrassonografia perineal, as modificações da junção uretrovesical (JUV) e da uretra proximal (UP) promovidas pela cirurgia combinada de Marshall-Marchetti-Krantz-Burch (MMK-B). MÉTODOS: foi realizado um estudo de intervenção longitudinal e prospectivo. Trinta e duas mulheres com incontinência urinária de esforço foram submetidas à ultrassonografia perineal antes e 30 dias depois da cirurgia para avaliar a distância pubo-uretral (DPU), o comprimento da uretra proximal (UP), a distância horizontal da JUV (DHJUV) e a distância vertical da JUV (DVJUV), estando a paciente em repouso, e os seus deslocamentos durante a manobra de Valsalva. Os resultados foram expressos em médias e desvios padrão. Para a comparação dos resultados do pré aos do pós-operatório, foi usado o teste t de Student para amostra pareada quando as variáveis cumpriam os critérios do teste de normalidade, e o teste pareado de Wilcoxon quando não cumpriam. RESULTADOS: em comparação às medidas do pré-operatório, a cirurgia de Marshall-Marchetti-Krantz-Burch reduziu a DPU no repouso (13,4 mm x 10,2 mm) e no esforço (19,8 mm x 9 mm); reduziu a DHJUV no repouso (14 mm x 4,3 mm) e no esforço (20,8 mm x 6,4 mm); aumentou o comprimento da UP no repouso (16,7 mm x 19,7 mm) e no esforço (1,6 mm x 15,4 mm); aumentou a DVJUV no esforço (-5,4 mm x 14,8 mm). A cirurgia de MMK-B não alterou a DVJUV no repouso (16,2 mm x 18,7mm, p=0,085). CONCLUSÕES: a cirurgia de Marshall-Marchetti-Krantz-Burch reduziu significativamente a mobilidade vertical e horizontal da junção uretrovesical, porém sem elevar a junção uretrovesical.

Respostas a uma crítica marxista às perspectivas retórica e pragmática em economia

Answers to a marxist critic of the rhetorical and pragmatic perspectives in economics. Based on recent discussions regarding the rhetorical perspective in economics, this paper presents an interpretation of the philosophical approach of Habermas which attempts to rescue the so called 'modern spirit', forgotten in the annals of the 19th century, similar to that presented by Marshall Berman in 1982. Following the reconstructive approach of Habermas's project of modernity, we attempt to show how a 'rhetorical approach' could be applied in the field of economics, and yet still be clearly modern by taking into account intersubjectivities, given the expanded sphere of human communication (as defended in the theory of communicative action of Habermas). In this sense, we will seek to demonstrate the philosophical limits of the anti-rhetorical critiques of, for example, Paulani (1996, 2003, 2005, 2006), which seem to underestimate the linguistic and intersubjective aspect of Habermas's philosophical project that can also be found in McCloskey’s methodological approach.

Marshall e os críticos à economia política clássica

Marshall and the critics to the classical political economy. This paper analyzes the period of transition between the millian orthodoxy and the marshallian orthodoxy with special emphasis on the influence of the economic debates of the 1870's and 1880's in the genesis of Marshall's conceptions. It is argued that in these decades Political Economy was questioned in three different fronts: by the theoretical critics, by the adepts of the historical method, and by the humanists. It is also argued that Marshall answered these criticisms, sometimes by accepting and incorporating them, sometimes by rejecting them, and in doing so he was able to construct a new disciplinary consensus - that gave the foundations to the practice of the next generation of economists.

Continuidade ou ruptura? Uma análise de alguns aspectos da filosofia social de John Stuart Mill, Alfred Marshall e John Maynard Keynes

O artigo argumenta que é possível se falar em uma 'tradição' no campo de filosofia social e econômica unindo as obras de J.S. Mill e Alfred Marshall e J.M. Keynes. Essa 'tradição' pode ser caracterizada pelas seguintes concepções: (a) pela rejeição moral aos valores aquisitivos do capitalismo; (b) pela visão de que o sistema capitalista seria incapaz de resolver de forma espontânea as questões das desigualdades de renda e riqueza e da pobreza; (c) pela ideia de que, por uma questão de garantia de liberdade e da diversidade, além de por questões de eficiência econômica, dever-se-ia deixar a iniciativa individual agir livremente nas esferas em que é capaz de engendrar bons resultados, mas que o Estado deveria intervir, quando essa falha, atuando em benefício da coletividade; (d) pela crença de que seria possível melhorar significativamente esse sistema por meio de mudanças pontuais e graduais.
