Amostras de sedimentos de fundo foram coletadas e analisadas para o mercúrio no Estuário de Santos-SP. Os resultados analíticos foram revistos para contaminação antropogênica de alguns setores da área estuarina como resultado de resíduos petroquímico e metalúrgico derivados do distrito industrial de Cubatão, das atividades siderúrgicas do Estado de São Paulo (COSIPA), do porto de Santos e, finalmente, das descargas dos efluentes do emissário submarino dentro da baía de Santos. Os valores para o fator de contaminação médio (FC) obtidos para os sedimentos de fundo variam de 1 a 3, principalmente para os canais de Santos e São Vicente; entretanto, na baía de Santos, os valores de FC (abaixo de 1) indicam baixa contaminação, exceto na área de descarga do emissário submarino.

A análise de dados termohalinos e correntes medidos em uma estação fixa no Canal de Piaçaguera (Estuário de Santos) no inverno foi feita em termos de condições cíclicas da maré (quadratura e sizígia) e quase-estacionária, com o objetivo de caracterizar a estratificação da massa de água estuarina, sua circulação e transporte de sal forçados pela modulação quinzenal da maré. Foram utilizados métodos clássicos de análise de dados observacionais horários e quase sinóticos e de simulações analíticas de perfis estacionários de salinidade e do componente longitudinal da velocidade. Durante o ciclo de maré de quadratura as velocidades de enchente (v<0) e vazante (v>0) variaram de -0.20 m/s a 0.30 m/s, associadas à pequena variação de salinidade entre a superfície e o fundo (26.4 psu a 30.7 psu). No ciclo de sizígia a velocidade aumentou de -0.40 m/s a 0.45 m/s, mas a estratificação de salinidade permaneceu praticamente a mesma. Os perfis estacionários teóricos de salinidade e de velocidade apresentaram boa concordância (Skill próximo a 1,0) quando comparados aos perfis observacionais. Durante a modulação quinzenal da maré não houve alteração na classificação do canal estuarino (tipo 2a-parcialmente misturado e fracamente estratificado), pois a taxa de aumento da energia potencial não foi suficiente para ocasionar a erosão da haloclina. Esses resultados, associados à alta estabilidade vertical (RiL >20) e ao número de Richardson estuarino (1,6), permitem as seguintes conclusões: i) o mecanismo que forçou a circulação e os processos de mistura foi principalmente o balanço da descarga fluvial com a maré, associado ao componente baroclínico da força de gradiente de pressão; ii) não houve variações nas principais características termohalinas e da circulação devido à modulação quinzenal da maré; e iii) os perfis quase estacionários de salinidade e da velocidade foram adequadamente simulados com um modelo analítico clássico.

The purpose of this article is to identify the contributions of Information Systems (IS) for environmental management practices, as well as the opportunities and challenges in this relation. Thus, we performed two case studies with Brazilian enterprises certified ISO 14001, by conducting interviews, document analysis and direct observation. As results, we present the identification of the main contributions of information systems for environmental management practices in the studied cases, the verification that a more advanced stage regarding IS is a factor that implies a more effective contribution, besides finding challenges and opportunities in this relation. The main contribution of this research consists of the presentation of a framework that identifies the support of information systems for environmental practices.

The city of Santos always had its importance recognised by the respectful role of flowing off the coffee production between the end of 19th and beginning of 20th centuries. All effervescence of this period brought changes to the central area of the city, located near the port. Beginning in the 1970s, some changes in the politics and in the city's urban space made its cafes, theaters, stores and traditional residencies find itselves in decadence imposed by the negligence of the public power. The Historic Downtown of Santos changed to a forgotten and depreciated space and remained that way for many years, reflecting negatively in the preservation of the arquitetonic heritage of the city. The present project aims to analyse the transformation of the current space of the Hitoric Downtown of Santos from the beginning of the 20th century and its recent revaluation through the public politics of the city

O Porto de Santos, o maior e mais importante porto da América Latina, é afetado por diversos problemas que também afligem muitos portos no Brasil e no mundo, como o trânsito complicado, estacionamentos mal planejados, áreas abandonadas, deterioração das áreas urbanas próximas ao porto, além da falta de interação entre porto e a cidade, resultando em um espaço totalmente dissociado de sua vizinhança. Trabalhando o conceito do turismo na região, este trabalho propõe a revitalização e a requalificação de áreas deterioradas e ociosas da zona portuária, cuja área de atuação se concentra na faixa entre o Terminal Marítimos de Passageiros do Porto de Santos (Concais) e a área próxima ao Ferry Boat, onde ocorre a Travessia de Balsas Santos-Guarujá, propondo uma experiência única tanto para os cidadãos santistas, como para o turista que desembarca no Concais e pretende conhecer outras partes da cidade ou mesmo as praias do Guarujá. Com isso propõe a implantação de áreas ajardinadas e praças, e equipamentos de lazer e turismo entre outros, beneficiando a população, otimizando a atividade portuária e gerando mais ônus para a cidade, além de finalmente integrar eficientemente a área portuária à urbana, destacando cada vez mais os pontos fortes e característicos da cidade

Governament organizations has as challenge for their governance the requirement ro improve evaluation system that measure the acting of their mediations and profefer for society informations about achievements. The text analyze the challenges and advances of evaluation tools for produce guidelines that could be inserted at context of decision-making from public agents. Thereunto informations must be reliable and real-time, creating vectors of haste for modernization of informational capacity of State as a whole.

The aim of this work is to advance a new approach for estimating demographic density, through combining a Geographic Information System with GMDH Neural Networks. The model that is suggested parts the analyzed space into a rectangular grid formed by multiple cells measuring 0.01 km2 each. The forecasts are elaborated based on the demographic density in each cell and in its neighboring cells at a given time. Despite the limited availability of data during the modeling phase, the utilization of this method for studying a Brazilian medium-sized city presented promising results.

Analysis of thermohaline properties and currents sampled at an anchor station in the Piacaguera Channel (Santos Estuary) in the austral winter was made in terms of tidal (neap and spring tidal cycles) and non-tidal conditions, with the objective to characterize the stratification, circulation and salt transport due to the fortnightly tidal modulation. Classical methods of observational data analysis of hourly and nearly synoptic observations and analytical simulations of nearly steady-state salinity and longitudinal velocity profiles were used. During the neap tidal cycle the flood (v<0) and ebb (v>0) velocities varied in the range of -0.20 m/s to 0.30 m/s associated with a small salinity variation from surface to bottom (26.4 psu to 30.7 psu). In the spring tidal cycle the velocities increased and varied in the range of -0.40 m/s to 0.45 m/s, but the salinity stratification remained almost unaltered. The steady-state salinity and velocity profiles simulated with an analytical model presented good agreement (Skill near 1.0), in comparison with the observational profiles. During the transitional fortnightly tidal modulation period there was no changes in the channel classification (type 2a - partially mixed and weakly stratified), because the potential energy rate was to low to enhance the halocline erosion. These results, associated with the high water column vertical stability (RiL > 20) and the low estuarine Richardson number (RiE = 1.6), lead to the conclusions: i) the driving mechanism for the estuary circulation and mixing was mainly balanced by the fresh water discharge and the tidal forcing associated with the baroclinic component of the gradient pressure force; ii) there was no changes in the thermohaline and circulation characteristics due to the forthnigtly tidal modulation; and iii) the nearly steady-state of the vertical salinity and velocity profiles were well simulated with a theoretical classical analytical model.
