Influência da temperatura e da energia de compactação nos parâmetros obtidos em ensaios no âmbito na marcação CE de misturas betuminosas

Em Portugal, grande parte da rede rodoviária é constituída por pavimentos flexíveis a quente, os quais têm vindo a ser alvo de um estudo exaustivo devido ao elevado aumento do tráfego registado nos últimos anos. Todos os estudos realizados em misturas betuminosas, após 1 de Março de 2008, utilizam as normativas da marcação CE, estabelecidas pela União Europeia no Âmbito da Directiva Comunitária nº 93/465/CEE e têm como objectivo garantir aos utentes que os materiais utilizados foram produzidos de forma controlada, de acordo com os requisitos definidos. Este trabalho teve como principal objectivo avaliar a influência da temperatura e da energia de compactação nas Misturas Betuminosas. Nesse intuito, estudaram‐se diferentes formulações das Misturas Betuminosas, nas quais se fez variar a temperatura e a energia de compactação. Neste trabalho apresentam‐se as formulações propostas, os ensaios realizados segundo a Marcação CE e a análise dos resultados obtidos. Executou‐se, também, o ensaio Marshall de forma a estudar e avaliar o desempenho da mistura. Pressupõe‐se que a variação da temperatura numa mistura betuminosa é bastante importante por ser responsável pelo comportamento dos betumes, o qual se reflecte na mistura originando variações no respectivo comportamento mecânico que serão tanto maiores quanto maior for a percentagem de betume da mesma. A energia de compactação tem como objectivo reduzir o índice de vazios da mistura através do rearranjo das partículas, originando desse modo uma diminuição da camada da mistura betuminosa, responsável pela melhoria do comportamento mecânico e funcional da camada.

Noise management at work

Every single day millions of European workers are exposed to noise at work. One in five of European’s workers have to raise his voice to be heard for at least half of the time that there are at work and 7% suffer from work-related hearing impairment. In Europe noise-induced hearing loss is the most common reported occupational disease. This paper deals with issues related with noise management at work, especially regarding the compliance with the new noise European Directive, (2003/10/EC).

Auditorias energéticas – definição de um plano de ação para edifícios de serviços

O setor dos edifícios representa perto de 40% do consumo de energia final na Europa e cerca de 30% no caso de Portugal [1]. Para fazer face a esta situação foi elaborada e aprovada uma Diretiva Europeia Relativa ao Desempenho Energético dos Edifícios, que foi transposta a nível nacional através de um pacote legislativo assente em três pilares, nomeadamente o Sistema Nacional de Certificação Energética e da Qualidade do Ar Interior (SCE), o Regulamento dos Sistemas Energéticos de Climatização em Edifícios (RSECE) e o Regulamento das Características de Comportamento Térmico dos Edifícios (RCCTE). Atuando ao nível da eficiência energética o consumo de energia nos edifícios pode diminuir para metade, para tal é necessário proceder-se à execução de auditorias energéticas para poder determinar as soluções mais adequadas de forma a reduzir os desperdícios e custos associados ao consumo de energia. Nesta dissertação desenvolveu-se uma metodologia para a realização de auditorias energéticas em edifícios que assenta essencialmente em cinco etapas, nomeadamente: o planeamento, a análise do estado atual, o planeamento estratégico, a elaboração de relatório e a implementação de medidas com acompanhamento de resultados. A aplicação desta metodologia constitui uma grande ajuda na realização de auditorias energéticas conferindo uma maior qualidade à sua execução. De forma a validar a metodologia efetuada foi realizado o estudo de três casos práticos relativos a três agências bancárias (denominadas de A, B e C), em que duas delas pertencem a um projeto de eficiência energética que engloba 50 agências e uma outra que pertence a um outro projeto de apenas 3 agências. A metodologia segue a mesma lógica para as três agências, no entanto, em termos de validação, a última instalação baseia-se nos consumos dos dados monitorizados em contínuo.

O princípio da confidencialidade na mediação em matéria civil e comercial

The purpose of the following study is to analyze the relevance of the principle of confidentiality concerning mediation on civil and commercial matters developed in Portugal. We will, essentially, try to determine just how pivotal is this principle and how it affects the effectiveness of that method of alternative dispute resolution. We believe it is fundamental to understand the true extent of this principle and its goals, emphasizing the protection given to those who decide to resort to mediation and its impact on this process. For this dissertation, we have based our analysis on the interpretation of the set rules assembled by Law nr 29/2013, April 19th, while combining it with data gathered from other laws and regulations that had also addressed mediation. Furthermore, given the fact that this subject has been regulated by Directive 2008/52/EC, we deem pertinent to include references to other European mediation regulations, namely from Germany, Spain and France. With this study, we have established that, even though the Portuguese mediation law is based on a European Directive, we have determined a more restrictive regulation for the principle of confidentiality. We have concluded that the rules regarding this principle try to preserve, above all, the trust and honesty established during the course of the mediation, while restricting the possibility of using the information disclosed during these sessions on other cases. Additionally, we believe confidentiality is such a distinctive and relevant feature that its legal framework leads us to deem it as a true obstacle to the parties’ private autonomy and their power to determine how the mediation should be carried out.

IPH response to the Joint Committee on Health and Children and members of the Northern Ireland Assembly on “Cross-border cooperation on healthcare”

The Institute of Public Health in Ireland were asked to submit a paper on 'Cross-border cooperation on healthcare' for a joint meeting between the Oireachtas Joint Committee on Health and Children and the Northern Ireland Assembly Health Committee which took place in Leinster House on 1 March 2012. Key points from the submission included: o    The Institute of Public Health in Ireland (IPH) is an all-island organisation which promotes cooperation between the Republic of Ireland and Northern Ireland with the aim of improving population health on the island and tackling health inequalities. IPH work is focused on addressing the causes of ill health rather than the design and delivery of treatment services. o    North/South cooperation on health was mandated under the Belfast Agreement in 1998 in five domains, including health promotion. IPH has supported the North South Ministerial Council (NSMC) in respect of the health promotion strand since inception. o    The Department of Health and Department of Health, Social Services and Public Safety North-South Feasibility Study (December 2011) states that mutual benefits are most evident from cooperation in the areas of (i) anticipating trends and illnesses in a collective manner (ii) public health issues (iii) specialised services where the population or activity required to sustain the service cannot be met by either jurisdiction alone and (iv) in relation to those areas adjacent to the border. o    The European Directive on Cross-Border Healthcare will be implemented in the next few years which will have implications in relation to patients travelling for healthcare across the Republic of Ireland/Northern Ireland border. o    IPH is supporting the development of new public health strategies in the Republic of Ireland and Northern Ireland which are both due for publication this year. o    There are tangible benefits from cross-border cooperation in the health sector, both in public health and in health service planning and delivery and there are many examples of successful initiatives. However, developments are not occurring in the context of an agreed plan or overall strategic context and tend to be project-based and concentrated in border counties. o    Successful cross-border cooperation requires high level support and integration into departmental policy cycles. The provision of data on an all-island basis supports cross-border cooperation as does the operation of sustainable all-island organisations which can support research, evaluations and programmes. o    In the future, cross-border cooperation in health will be more effective if developed with a strategic planning process intrinsically linked to Departmental priorities. o    North-South cooperation in the areas of alcohol, obesity, tobacco health surveys and rare diseases will be particularly beneficial.

La transposició de la Directiva 2001/29/CE sobre drets d'autor i l'impacte sobre les biblioteques i centres similars : elements per al debat

A Espanya encara tenim pendent la transposició de la Directiva 2001/29/CE "relativa a la armonización de determinados aspectos de los derechos de autor y derechos afines a los derechos de autor en la sociedad de la información", la qual suposarà una modificació del marc legal que regula aquesta matèria. En aquest article s'analitzen els aspectes de la Directiva que més poden afectar el desenvolupament dels serveis que ofereixen les biblioteques i centres similars, prestant atenció als punts que poden ser més conflictius a la llum de les dues propostes que fins al moment s'han plantejat.

Calidad microbiológica de las aguas de baño del embalse Conde del Guadalhorce, de Málaga (España), 2000-2005.

Background. Determine the presence and evolution of indicators microorganisms of water pollution in “Conde del Guadalhorce” reservoir, Málaga city, Spain. A second objective was to analyze pollution degree and evaluate the sanitary quality of bathing water and compliance with European Directive 76/160/CE. Method. A total of 120 water samples were collected in two bathing freshwater sites during May to September sampling period between 2000 to 2005, and the numbers of total coliforms (CT), faecal coliforms (CF) and faecal streptococci (EF) were enumerated using the membrane filtration method. We used the log-normal distribution method and calculate the logarithmic means, percentile points, ratios CF:EF, ANOVA and Pearson correlations. Results. Only two samples overcome CF limit values at Camping sampling station during 2000 year. Ratios CF:EF values were higher (> 4) during 2000 to 2002, and lower (< 0,7) during 2003 to 2005. Significant differences (ANOVA F = 3,41, ∝ < 0,01) was only observed with EF during evaluated period. There was no significant difference between concentration means at bathing water sites (ANOVA, F = 3,395, ∝ < 0,01). The counts of CT and CF were significantly correlated in Kiosko water samples, while in Camping water, significant correlation (t = 0,632, p < 0,05) was only observed with EF at the Camping station during 2000, 2003 and 2005 years. Conclusions. “Conde del Guadalhorce” reservoir showed hygienic conditions for safety bathing. Globally, water bathing quality is good. CT, CF y EF indicators were agreed with UE Directive during 2000- 2005, with exception CF at Camping station in 2000 year. CT y CF concentrations at Camping were frecuently higher than Kiosko, it could be caused to swimmers abundance and recreational activities. There was a trend towards rising EF, it could be caused to faecal pollution source of animal origin, needed to research it.

Spanish auditors and the 'true and fair view'

In 1990 a new Spanish 'Plan General de Contabilidad' (PGC) implementedthe requirements of the EU 4th and 7th Directives in Spain. Included in the PGC is the requirement, derived from the 4th Directive, that accounts should present a 'true and fair view', in Spanish 'imagen fiel'. Where the term has been used in English speaking jurisdictions it has proved to have a variety of shades of meaning, and to have had strikingly different impact in different countries. Within the European Union the term has been seen as a 'Trojan horse', inserted into the 4th Directive to inject an Anglo-Saxon approach of flexibility and judgement dependent accounting into a Continental European accounting tradition of detailed prescription and uniformity. In this paper we report on a survey of the views and experience of Spanish auditors relating to 'imagen fiel'. Specifically, we:1) Review the English language literature on 'true and fair view' to identify the key areas of controversy.2) Consider the significance of the 'true and fair view' within the EU 4th Directive.3) Report on the experience of Spanish auditors in working with this concept, their views on the value of the term, and their experience in use of the true and fair view 'override'.

Validação do método de determinação simultânea dos íons brometo e bromato por cromatografia iônica em águas de consumo humano

European Directive (98/83/CE), compulsory after 2008, states that bromate in drinking water must be controlled at levels below 10 mg L-1. Supporting implementation of the Directive, the European Comission has established project SMT4-CT96 2134, in collaboration with various european institutions, aiming at the identification of the interferents to the current analytical method (Ionic Chromatography with Conductimetric Detection - IC/CD), their removal and the automation of pre-treatment and injection steps, as well as the development of alternative methods. EPAL, responsible for the water supply to a great deal of Portuguese regions, has taken steps to meet these requirements. Although not part of such project, this work (the result of a project conducted under a protocol of collaboration between EPAL SA and FCUL - Faculty of Sciences, University of Lisbon), reports on studies of usefulness to laboratories planning to monitor bromate in ozone treated waters, in conditions different from those described in EPA 300.1. Simultaneous determination of bromide is justified by its role as bromate precursor.
