Responsiveness summary : United States Army Corps of Engineers : Waukegan Harbor, Lake County, Illinois : Section 401 water quality certification for dredging of the Waukegan Harbor approach channel and advanced maintenance area.

The approved project allows the Corps to dredge the Waukegan Harbor approach channel and advanced maintenance area. The area to be dredged lies immediately east of the north breakwater. It is approximately a rectangle 650 feet north and south and 1,400 feet east and west. The advanced maintenance area is a band along the north side of the channel. The approved project is for a 10-year certification, under which the Corps may remove 22,000 to 75,000 cubic yards of sediment per dredging event. The dredging depth is 22 feet and the amount to be dredged is about one foot of sediment. As a condition of the certification, disposal of the dredged sediment in Lake Michigan or the waters of the state cannot occur until the conditions of the certification are met. These conditions, which have been placed on the certification by Illinois EPA, ensure that the project meets state water quality standards and is consistent with the determinations of the Illinois Attorney General's Task Force on asbestos contamination at Illinois Beach State Park.

Integração de atiradores especiais num batalhão de Infantaria

O presente trabalho de investigação subordinado ao tema “A integração de Atiradores Especiais num Batalhão de Infantaria” propõe investigar a integração de atiradores especiais numa unidade escalão Batalhão de Infantaria. Para a sua consecução definiu-se como objetivo geral analisar as implicações do emprego de atiradores especiais, no atual ambiente operacional, em apoio às unidades escalão Batalhão de Infantaria. De modo a concretizar o mesmo delimitou-se o trabalho ao estudo dos Batalhões de Infantaria Mecanizados de Rodas, da Brigada de Intervenção, recorrendo-se sempre que necessário aos Batalhões Stryker do Exército dos Estados Unidos da América, dada a sua experiência de combate em diversos teatros de operações. Para a realização deste trabalho estruturou-se um modelo de análise, efetuando-se uma abordagem qualitativa de natureza descritiva. Recorre-se ao método de abordagem hipotético-dedutivo, através de uma conexão descendente iniciada com a descrição do ambiente operacional, o emprego de Batalhões de Infantaria e a utilização de atiradores especiais. Da análise dos resultados verifica-se que o atual ambiente operacional apresenta uma elevada complexidade, existindo uma tendência para os futuros conflitos armados ocorrerem em Estados falhados e em áreas urbanas, existindo uma ameaça predominantemente irregular. Os Batalhões de Infantaria têm assim a necessidade de possuir atiradores especiais, de forma a poderem empregar fogos diretos com precisão. Conclui-se que com a crescente complexidade do ambiente operacional face à tipologia de ameaça, os Batalhões de Infantaria portugueses, que futuramente poderão ser empregues neste tipo de teatros de operações, devem possuir atiradores especiais, que empreguem fogos diretos com precisão a médias distâncias, sendo estes integrados ao nível das Secções de atiradores.

A participação de Portugal no Teatro de Operações Kosovo : O caso do 1º Batalhão de Infantaria Mecanizado

O Teatro de Operações Kosovo localiza-se numa região caraterizada por séculos de confluência de rotas comerciais, culturas, etnias e religiões distintas e que, por essa e outras razões tem sido assolada por inúmeros conflitos. Numa fase pós Guerra Fria, as forças internacionais, dada a escalada da violência, intervieram neste cenário integrando também forças portuguesas, entre as quais e por diversas vezes, o 1º Batalhão de Infantaria Mecanizado. Desde o início desta intervenção, desde os finais da década de noventa, até à atualidade, o teatro de operações referido experimentou diversas alterações de cariz social, politico e étnico que se traduziram por vezes em conflitos e fenómenos violentos. Dada a intervenção portuguesa num ambiente de conflitualidade volátil e em permanente mutação, inserida no âmbito das Missões de Apoio à Paz, o trabalho de investigação desenvolvido assume como objetivo descrever as alterações ao nível do emprego do 1º Batalhão de Infantaria Mecanizado, para fazer face à tipologia Kosovo do período pós Guerra Fria (2000-2014). Pretende-se que estas alterações sejam compreendidas e interpretadas através da implementação de um modelo de análise baseado nos fatores de decisão militares1, que sistematiza e organiza informação constante em documentos resultantes de cada um dos empenhamentos abordados, bem como no depoimento de militares presentes nesses mesmos contextos, no período abordado. No que a este último aspeto concerne, a aplicação do método indutivo usando como instrumento de opção metodológica o Estudo de Caso, permite a recolha de dados qualitativos resultantes das respostas obtidas nas entrevistas semiestruturadas, a militares presentes no Kosovo no período compreendido entre 2000 e 2014. Após toda a investigação realizada, parecem ganhar evidência alterações ao nível do emprego do 1º Batalhão de Infantaria Mecanizado no TO Kosovo, evidências essas materializadas nos fatores Missão, Ameaça, Tarefas, Viaturas, Efetivo e Orgânica, como consequência quer das restruturações efetuadas da Kosovo Force (KFOR), quer das oscilações de conflitualidade inerentes ao próprio teatro, que, ao longo do lapso de tempo estudado, atravessou períodos de menor e maior estabilidade.

Analytical solution of forced convection in a duct of rectangular cross-section saturated by a porous medium

A theoretical analysis is presented to investigate fully developed (both thermally and hydrodynamically) forced convection in a duct of rectangular cross-section filled with a hyper-porous medium. The Darcy-Brinkman model for flow through porous media was adopted in the present analysis. A Fourier series type solution is applied to obtain the exact velocity and temperature distribution within the duct. The case of uniform heat flux on the walls, i.e. the H boundary condition in the terminology of Kays and Crawford [1], is treated. Values of the Nusselt number and the friction factor as a function of the aspect ratio, the Darcy number, and the viscosity ratio are reported.

Atelectasis observed by computerized tomography after Caesarean section

Atelectasis after either vaginal or Caesarean delivery has not been adequately quantified. This study addresses the hypothesis that atelectasis may be worse in women who undergo Caesarean section when compared with vaginal delivery under regional anaesthesia. Twenty healthy non-smoking women submitted to a chest computed tomography (CT) 2 h after delivery in a University Hospital, who had experienced vaginal delivery (n=10) under combined spinal-epidural analgesia or a Caesarean section (n=10) under spinal anaesthesia, were evaluated. The percentage cross-sectional area of atelectasis in dependent lung regions were measured from the CT images obtained at cross-section of the xiphoid process and the top of the diaphragm. The percentage cross-sectional area of atelectasis was 3.95% in the vaginal delivery group and 14.1% in the Caesarean group (P < 0.001, Mann-Whitney rank sum test). These results suggested that pulmonary atelectasis is greater after Caesarean section delivery under spinal anaesthesia than after vaginal delivery with combined spinal-epidural analgesia.

Service Provision for visually disabled adults by Social Service Departments in Portugal and England: a Comparative Perspective

Este artigo apresenta os principais resultados de um estudo de casos realizado sobre a prestação de serviços para adultos com deficiência visual pelos departamentos de acção social das autarquias em Portugal e Inglaterra. Emergiu da pesquisa que existem diferenças significativas nos serviços prestados aos adultos com deficiência visual tendo em conta que os departamentos de acção social daqueles dois países estão estruturados diferentemente e existem dentro de uma estrutura económica, social, cultural e política diferente. No entanto, podemos concluir que em Inglaterra a oferta de bens e serviços pelas instâncias municipais é mais abrangente, especializada e tem uma longa história de existência. Pelo contrário em Portugal o Estado-Providência tem uma história recente, e às autarquias é atribuído um papel suplementar no que diz respeito à prestação de serviços para pessoas com deficiência visual.

Short-term wind power forecasting in Portugal by neural networks and wavelet transform

This paper proposes artificial neural networks in combination with wavelet transform for short-term wind power forecasting in Portugal. The increased integration of wind power into the electric grid, as nowadays occurs in Portugal, poses new challenges due to its intermittency and volatility. Hence, good forecasting tools play a key role in tackling these challenges. Results from a real-world case study are presented. A comparison is carried out, taking into account the results obtained with other approaches. Finally, conclusions are duly drawn. (C) 2010 Elsevier Ltd. All rights reserved.

Occupational exposure to Aspergillus by swine and poultry farm workers in Portugal

Aspergillus is among a growing list of allergens that aggravate asthmatic responses. Significant pulmonary pathology is associated with Aspergillus-induced allergic and asthmatic lung disease. Environments with high levels of exposure to fungi are found in animal production facilities such as for swine and poultry, and farmers working with these are at increased risk for occupational respiratory diseases. Seven Portuguese poultry and seven swine farms were analyzed in order to estimate the prevalence, amount, and distribution of Aspergillus species, as well as to determine the presence of clinical symptoms associated with asthma and other allergy diseases in these highly contaminated settings. From the collected fungal isolates (699), an average incidence of 22% Aspergillus was detected in poultry farms, while the prevalence at swine farms was 14%. The most frequently isolated Aspergillus species were A. versicolor, A. flavus, and A. fumigatus. In poultry farms, A. flavus presented the highest level of airborne spores (>2000 CFU/m3), whereas in swine farms the highest was A. versicolor, with an incidence fourfold greater higher than the other mentioned species. Eighty workers in these settings were analyzed, ranging in age from 17 to 93 yr. The potentially hazardous exposure of poultry workers to mold allergens using sensitization markers was evaluated. Although no significant positive association was found between fungal contamination and sensitization to fungal antigens, a high incidence of respiratory symptoms in professionals without asthma was observed, namely, wheezing associated with dyspnea (23.8%) and dyspnea after strenuous activities (12.3%), suggesting underdiagnosed respiratory disturbances. Further, 32.5% of all exposed workers noted an improvement of respiratory ability during resting and holidays. From all the analyzed workers, seven were previously diagnosed with asthma and four reported the first attack after the age of 40 yr, which may be associated with their occupational exposure. Some of the fungi, namely, the Aspergillus species detected in this study, are known to induce hypersensitivity reactions in humans. This study confirmed the presence and distribution of Aspergillus in Portuguese poultry and swine farms, suggesting a possible occupational health problem and raising the need for preventive and protective measures to apply to avoid exposure in both occupational settings.

Risk factors for cesarean section by category of health service

OBJECTIVE: To analyze the rate of cesarean section and differences in risk factors by category of health service, either public or private. METHODS: A cross-sectional study was carried out including all pregnant women in labor admitted to hospitals in the city of Rio Grande, Southern Brazil, between January 1 and December 31, 2007. A pre-coded and pre-tested questionnaire was used to collect on social, demographic, obstetric and newborn care information. Two regression models were constructed: one for public users and the other one for private ones. Poisson regression was used in each model in the multivariate analysis. Prevalence rates and 95% confidence intervals were calculated for each adjusted factor. RESULTS: The rate of cesarean section was 43% and 86% among public and private users. Sociodemographic factors and twin births have a more significant impact among public users as well as number of pregnancies (25% vs. 13% reduction in public and private users, respectively) and previous cesarean section (86% vs. 24% increase in public and private users, respectively). Prenatal care visits and hospital admissions affected the outcome only in women users of public services. CONCLUSIONS: Cesarean section rates were high in both groups studied, but it was twice as high among women cared in the private sector. Associated factors differ in magnitude by category of service used.

Legal and political regulation of higher education in Portugal: an evolutionary perspective on the current policy issues and the problem of order

The higher education system in Europe is currently under stress and the debates over its reform and future are gaining momentum. Now that, for most countries, we are in a time for change, in the overall society and the whole education system, the legal and political dimensions have gained prominence, which has not been followed by a more integrative approach of the problem of order, its reform and the issue of regulation, beyond the typical static and classical cost-benefit analyses. The two classical approaches for studying (and for designing the policy measures of) the problem of the reform of the higher education system - the cost-benefit analysis and the legal scholarship description - have to be integrated. This is the argument of our paper that the very integration of economic and legal approaches, what Warren Samuels called the legal-economic nexus, is meaningful and necessary, especially if we want to address the problem of order (as formulated by Joseph Spengler) and the overall regulation of the system. On the one hand, and without neglecting the interest and insights gained from the cost-benefit analysis, or other approaches of value for money assessment, we will focus our study on the legal, social and political aspects of the regulation of the higher education system and its reform in Portugal. On the other hand, the economic and financial problems have to be taken into account, but in a more inclusive way with regard to the indirect and other socio-economic costs not contemplated in traditional or standard assessments of policies for the tertiary education sector. In the first section of the paper, we will discuss the theoretical and conceptual underpinning of our analysis, focusing on the evolutionary approach, the role of critical institutions, the legal-economic nexus and the problem of order. All these elements are related to the institutional tradition, from Veblen and Commons to Spengler and Samuels. The second section states the problem of regulation in the higher education system and the issue of policy formulation for tackling the problem. The current situation is clearly one of crisis with the expansion of the cohorts of young students coming to an end and the recurrent scandals in private institutions. In the last decade, after a protracted period of extension or expansion of the system, i. e., the continuous growth of students, universities and other institutions are competing harder to gain students and have seen their financial situation at risk. It seems that we are entering a period of radical uncertainty, higher competition and a new configuration that is slowly building up is the growth in intensity, which means upgrading the quality of the higher learning and getting more involvement in vocational training and life-long learning. With this change, and along with other deep ones in the Portuguese society and economy, the current regulation has shown signs of maladjustment. The third section consists of our conclusions on the current issue of regulation and policy challenge. First, we underline the importance of an evolutionary approach to a process of change that is essentially dynamic. A special attention will be given to the issues related to an evolutionary construe of policy analysis and formulation. Second, the integration of law and economics, through the notion of legal economic nexus, allows us to better define the issues of regulation and the concrete problems that the universities are facing. One aspect is the instability of the political measures regarding the public administration and on which the higher education system depends financially, legally and institutionally, to say the least. A corollary is the lack of clear strategy in the policy reforms. Third, our research criticizes several studies, such as the one made by the OECD in late 2006 for the Ministry of Science, Technology and Higher Education, for being too static and neglecting fundamental aspects of regulation such as the logic of actors, groups and organizations who are major players in the system. Finally, simply changing the legal rules will not necessary per se change the behaviors that the authorities want to change. By this, we mean that it is not only remiss of the policy maker to ignore some of the critical issues of regulation, namely the continuous non-respect by academic management and administrative bodies of universities of the legal rules that were once promulgated. Changing the rules does not change the problem, especially without the necessary debates form the different relevant quarters that make up the higher education system. The issues of social interaction remain as intact. Our treatment of the matter will be organized in the following way. In the first section, the theoretical principles are developed in order to be able to study more adequately the higher education transformation with a modest evolutionary theory and a legal and economic nexus of the interactions of the system and the policy challenges. After describing, in the second section, the recent evolution and current working of the higher education in Portugal, we will analyze the legal framework and the current regulatory practices and problems in light of the theoretical framework adopted. We will end with some conclusions on the current problems of regulation and the policy measures that are discusses in recent years.

Action, reaction and protest by publishers in 1960s Portugal: books and other publications in the Catholic opposition

The authoritarian regime of the Portuguese Estado Novo (New State), the longest dictatorship in twentieth-century Western Europe, suffered one of its most serious threats during the late 1950s and the whole of the following decade. An array of events and dynamics of opposition to the regime and condemnation of the political and social situation in Portugal appeared at that time. One of the core groups that displayed their dissidence in the 1960s, with the awakening of their critical conscience, originated in Catholic sectors that rallied the laity and the clergy to express their disagreement or even break with the government of Salazar (and, later, Marcelo Caetano). This article aims to establish the role of print culture and, in particular, publishing in the opposition’s mobilisation of Catholics who criticised the Estado Novo. It will also closely examine the contribution of certain publishers to the formulation of the terms of this mobilisation, in publishing new authors and topics and creating new printed forums (e.g. periodicals) for discussion and reflection. The most detailed case will be that of the publishing house Livraria Moraes Editora, under the command of the publisher António Alçada Baptista.

Bio and magnetostratigraphy of two Lower Miocene sections, Tagus basin (Portugal)

The magnetostratigraphy of two sections in early Miocene marine deposits of the Tagus Basin is studied. Thermal demagnetization was used to isolate the primary component of magnetization for 45 samples from the Foz da Fonte section, and for 74 others from Trafaria section. The succession of the polarity zones found in these sections is tentatively correlated with the geomagnetic polarity time scale (GPTS) on the basis of the biostratigraphic data yielded by planktic Foraminifera. The planktic zones and magnetic polarities recognized in these sections can be adequately correlated with the part of the GPTS [table calibrated by BERGGRENET al. (1985)] corresponding to the Anomalies 6 and 5E (Foz da Fonte) and 5D (Trafaria). This correlations suggests ages between 19,35 and 18,14 Ma for Foz da Fonte section, and 17,90 to 16,98 Ma for Trafaria.
