Abstract

The objective of this work is to study the influence of different fluids of the tympanic cavity into the biomechanical behavior of the middle ear. The 3 D computer model of the tympanic ossicular chain was built using images from computed tomography (CT). After construction of the tympanic ossicular chain model, it was adapted the simulation by placing the passage to the external auditory canal and to the tympanic cavity.

The discretization of the model was made using the finite element method based on ABAQUS software. The mechanical properties were extracted from previous works. The umbo and the stapes footplate displacements, for a sound pressure level of 105 dB applied in tympanic membrane were obtained, comparing the tympanic ossicular chain and the different levels of external and internal pressure in the middle ear (liquid and air). The results demonstrate that the biomechanical behavior of the middle ear is different for different levels of pressure tested in this model. When using liquid, displacements are of lower amplitude when compared with the results obtained with air.

 

Abstract

Component: 1.1 Initial Assessment Sub-component: 1.1.4 Marine Environment Annex This Initial Assessment of anthropogenic pressures and impacts on ecosystems in OSPAR Region IV provides information on different types of pressures that are assessed under the Marine Strategy Framework Directive (MSFD). The main goal of the MSFD is to achieve Good Environmental Status (GES) of EU waters by 2020. GES is defined as “The environmental status of marine waters where these provide ecologically diverse and dynamic oceans and seas which are clean, healthy and productive”. GES is described by eleven Descriptors, including nine Descriptors that are related to anthropogenic pressures, belonging to “biological”, “physical” or “substances, litter and energy” categories. For each type of pressure, this document mentions activities driving this pressure, potentially impacted areas (areas subject to high levels of pressures), and if available also information on actual impacts of the pressure on ecosystems. This document did not assess ‘input of microbial pathogens’, ‘input of genetically modified species and translocation of native species’, ‘loss of, or change to, natural biological communities due to cultivation of animal and plant species’. As the knowledge on cumulative impacts is currently limited, this report is restricted to potential and actual impacts of each pressure on the ecosystem. This report was produced as part of SIMNORAT Project (Grant Agreement N0. EASME/EMFF/2015/1.2.1.3/03/SI2.742089). Competition for maritime space – for renewable energy equipment, aquaculture and other uses – has highlighted the need to manage our waters more coherently. Maritime spatial planning (MSP) works across borders and sectors to ensure human activities at sea take place in an efficient, safe and sustainable way. That is why the European Parliament and the Council have adopted a legislation to create a common framework for maritime spatial planning in Europe. The Directive 2014/89/EU of the European Parliament and of the Council of 23 July 2014 (said Maritime Spatial Planning Directive) establishes a framework in order to reduce conflicts between sectors and create synergies between different activities, to encourage investment – by creating predictability, transparency and clearer rules, to increase cross-border cooperation – between EU countries to develop energy grids, shipping lanes, pipelines, submarine cables and other activities, but also to develop coherent networks of protected areas, and to protect the environment – through early identification of impact and opportunities for multiple use of space. The SIMNORAT project (Supporting Implementation of Maritime Spatial Planning in the Northern European Atlantic) is an EU/DG Mare co-funded cross-border project. It was launched on 1st of January 2017 and involves Portugal, Spain and France, while these countries had just designated their Competent Authorities and transposed the Maritime Spatial Planning (MSP) Directive. SIMNORAT aims to support the implementation of the MSP Directive in the waters of Portugal, Spain and France, as well as to establish cross-border cooperation mechanisms between these Member States, to contribute to the coherence of their marine spatial plans to be established in 2021. The action ran until 31st of January 2019 and was based on a partnership of public bodies of the countries and one international organisation. It was composed of UAVR, CEDEX, IEO, AFB, CEREMA, Shom, and CPMR. Shom acted as coordinator. The objectives of the SIMNORAT project were addressed through a variety of activities and desktop or case studies. They are dedicated to identifying the methodology steps, and explore the challenges and opportunities of the MSP implementation in the Northern European Atlantic, including thus related to transboundary issues (Ecosystem based approach, marine policies, OSPAR Convention, Land Sea Interactions, geographical scale of the plans, data interoperability, tools to support MSP). The project led to a multiplicity of outputs including overviews of MSP relevant information related to the countries and on more focus areas, to a number of interviews and meetings where stakeholder views were collected to feed the reasoning, and to guidelines and good practices to be shared at a national and transnational level with marine stakeholders, scientific as well as planners, administrations and authorities. In addition, SIMNORAT permitted a lot of progression internally in the countries and regarding transboundary cooperation. It led to establish and develop new dialogues and to connect the technical or scientific actors, the stakeholders, the administrations of the countries of a same sea basin, and the administrations within the countries, including the representative of Regions. It allowed to better understand Maritime Spatial Planning mechanisms, to share knowledge and as such reached to build capacities, which is of importance as there is such a need in the Atlantic area compared to more Northern countries. The project also permitted to address topics which have never been addressed before. The involvement of France and Spain in SIMNORAT and in the EU-DG Mare sister projects SIMWESTMED and SIMCelt was useful for them to develop a global vision with their neighbours in the Western Mediterranean. At the end of this exercise, it is stated the need of pursuing the work and dialogue in particular through common tools, but at this stage, the SIMNORAT project has constituted a common knowledge and background.

Project manager Jesper H. Andersen This report contains, as said in the title, the supplementary material to the synthesis report from the ECOMAR project (2018- 2020). The supplementary material consists of three parts: 1) Annex A, being the data sets and layers dealing with human pressures and activities, 2) Annex B, being the data set related to ecosystem components and analogue data sets, and 3) Annex C, being additional data used for the mapping of potentially cumulative effects in Danish marine waters as well as maps of results mentioned, but not show in the synthesis report. For each data set, a specific reference to the data authoring organization as well as contact information for the Data Author. THE VELUX FOUNDATIONS
