Possible effects of secular resonances in Phobos and Triton

Due to the tides, the orbits of Phobos and Triton are contracting. While their semi major axes are decreasing, several possibilities of secular resonances involving node, argument of the pericenter and mean motion of the Sun will take place. In the case of Mars, if the obliquity (epsilon), during the passage through some resonances, is not so small, very significant variations of the inclination will appear. In one case, capture is almost certain provided that epsilon greater than or equal to 20degrees. For Triton there are also similar situations, but capture seems to be not possible, mainly because in S-1 state, Triton's orbit is sufficiently inclined (far) with respect to the Neptune's equator. Following Chyba et al. (Astron. Astrophys. 219 (1989) 123), a simplified equation that gives the evolution of the inclination versus the semi major axis, is derived. The time needed for Triton crash onto Neptune is longer than that one obtained by these authors, but the main difference is due to the new data used here. In general, even in the case of non-capture passages, some significant jumps in inclination and in eccentricities are possible. (C) 2002 Elsevier B.V. Ltd. All rights reserved.

Generalized point interactions in one-dimensional quantum mechanics

There is a four-parameter family of point interactions in one-dimensional quantum mechanics. They represent all possible self-adjoint extensions of the kinetic energy operator. If time-reversal invariance is imposed, the number of parameters is reduced to three. One of these point interactions is the familiar delta function potential but the other generalized ones do not seem to be widely known. We present a pedestrian approach to this subject and comment on a recent controversy in the literature concerning the so-called delta' interaction. We emphasize that there is little resemblance between the delta' interaction and what its name suggests.

Avaliação comparativa da eficácia de fitoterápicos e produtos químicos carrapaticidas no controle do boophilus microplus (Canestrini, 1887) por meio do biocarrapaticidograma

The aim of this research was to evaluate the efficacy of plant extracts and chemical products for the control of Boophilus microplus. Three commercial products for the control of Boophilus microplus were in vitro evaluated, chemical compounds of cypermethrin + DDVP and organophosphate as recomended by the manufacturer, and also four plant extracts, Azadirachta indica (1%), Cymbopogon densiflorus, Lippia alba and Ipomoea asarifolia at different concentrations. The results showed that the chemical compounds tested had efficacy lower than 95% against the Boophilus microplus samples in the experiment. The extracts of all plants have shown some biological activity in the mortality of ingurgitated females and inhibition of egg crash, however the extract of Azadirachta indica presented efficacy higher than 95% in all tested concentrations, being the best sample tested in this experiment.

Urban heat islands and electrical energy consumption

This study proposes the development of thermal and energy consumption maps to generate useful planning information. A residential neighbourhood in a medium-sized city was selected as the study area. In this area, 40 points were taken as urban reference points where air temperatures at the pedestrian level were collected. At the same time, rural temperatures made available by the city meteorological station were registered. Data of electrical energy consumption of the building units (houses and apartments) were collected through a household survey that was also designed to identify the users' income levels. Then, maps were developed so that the configuration of urban heat islands and electrical energy consumption could be visualised, compared and analysed. The results showed that the income level was the most important variable influencing electrical energy consumption. However, a strong relationship of the consumption with the thermal environment was also observed.

Trabalho e capital na Amazônia Oriental: movimento operário versus reestruturação produtiva no Complexo Albrás-Alunorte: 1990 – 2005

A presente dissertação aborda a reestruturação produtiva nas fábricas da ALBRÁS e da ALUNORTE, localizadas no município de Barcarena/PA, e como o movimento operário se contrapôs a este processo no período de 1990-2005. Através de um estudo da crise crônica da economia capitalista mundial, agravada pelos dois choques do petróleo, tenta-se explicar como foi possível a instalação na Amazônia Oriental de duas fábricas modernas, com um contingente operário altamente concentrado. Destaca-se o quanto o papel do Estado é fundamental para que esse processo ocorra. Também analisamos como a partir do fenômeno da “globalização” – que nada mais é do que uma fase superior do imperialismo –, e dos novos processos de organização do trabalho – principalmente o modelo toyotista –, o movimento operário e suas organizações foram colocados à prova por conta da flexibilização do trabalho, da precarização, da terceirização e subcontratação, que dificultaram na década de 90 as greves e ações da classe trabalhadora no Brasil e no mundo. Baseado em materiais bibliográficos, folhetos e em entrevistas com operários e dirigentes sindicais, o trabalho evidencia que a luta contra a reestruturação produtiva na ALBRAS foi mais intensa, inclusive com o método da greve, do que na ALUNORTE, porque a ALBRAS tinha dez anos à frente da ALUNORTE e foi o primeiro laboratório da CVRD na cidade de Barcarena. Contraditoriamente, foi na ALBRAS onde aconteceu a maioria das demissões no período estudado, antes e depois da privatização da CVRD. A dissertação procura mostrar o papel do Sindicato dos Metalúrgicos e dos Químicos nesse processo de luta contra a reestruturação produtiva nas fábricas da ALBRAS e da ALUNORTE.

Finanças comportamentais e a formação de bolhas especulativas

Economic crises caused by speculative bubbles are recurring in economic history but there is still no consensus on how it begins, grows and overflows. Economists and regulators seem to be inefficient in predicting and preventing this process, which is so detrimental to economic functioning. This failure proved to be obvious with the American subprime crises, which had great impact on various sectors of the U.S. economy. In this paper, we perform a literature review of the traditional theory of finance, mainly represented by the Efficient Market Hypothesis. According to this theory, asset prices always reflect their intrinsic value, assumption that doesn’t match the price boom followed by a crash, observed in the crisis generated by speculative bubbles. Finally, we present a new way to analyze this phenomenon, in the light of the investors’ behavioral aspects and the flaws inherent to the financial markets

Requalificação das Praças Monsenhor Sarrion e Nove de Julho e o novo Terminal Urbano de Integração

The Center squares of the middle cities many times don’t have adapted forms to the uses, which change time-to-time, then they turn abased. Through the study case of the Squares Monsenhor Sarrion and Nove de Julho, public squares on Presidente Prudente downtown, where many types of uses occur in the same space with function of organization and reception of several fluxes generated because the centrality caused from downtown. In this context, is necessary re-project the squares, with new purpose of an urban and landscape project, which generates harmonic spaces of passage and permanence, which values the public edifications in the around areas and re-qualified the form of the squares, adapting to the new uses: To organize the public transportation traffic, the urban terminal; to organize the vehicles traffic, the lowering of the Avenue Coronel Marcondes and, mainly, to organize the traffic of pedestrian, the continuity and the physic integration of the squares, through new forms, urban furniture and design to the downtown public spaces

Conexão cultura: um projeto de revitalização e reestruturação da estação ferroviária de Guaratinguetá

This work presents an intervention at the Guaratinguetá Railway Station and its surroundings, including this area in the urban context, at this moment isolated of the activities and citizen attentions, offering new activities on this commercial area. The selected area finds itself in a state of neglect and forgetfulness from the urban relations. Located between the periphery of the commercial center and the Paraiba do Sul River, the correlation is tension between the advancement of shops, the railway line, and the natural barrier of the Paraiba River. On the context of these limits, the railroad and the river stand as barriers for the center expansion and the flows that connect the old part of the town with the new part, which is growing and is called “post-city river”. These barriers have relegating properties around them to isolation, despite being located in the center. The area choice and this intervention seeks to break this isolation and the barrier flow, linking areas of opposite sides to form a leak through the barrier of the railway line. The pedestrian flow is prioritized in the project, this flow will be attracted by the program offered and by the new created areas, increasing the space utilization by users and breaking the isolation of urban activities. And entering the area in the context of life of city residents. The attraction of these new flows will be through the implementation of a Cultural Center, supplying a lack of city by spaces that offer this type of activity. Its implementation aims to attract and modify the activities of these spaces and the surrounding areas, one side facing the commercial center, and another facing the river, linking this two sides at the same time that this link provides the expansion of distance traveled and known
