Transthoracic impedance cardiography (ICG) is a non-invasive method for determination of hemodynamic parameters. The basic principle of transthoracic ICG is the measurement of electrical conductivity of the thorax over the time. The aim of the study was the analysis of hemodynamic parameters from healthy individuals and the evaluation of various hemodynamic monitoring devices. Fourteen men (mean age 25 ± 4.59 years) and twelve women (mean age 24 ± 3.5 years) were measured during the cardiovascular engineering laboratory at Offenburg University of Applied Sciences, Offenburg, Germany. The ICG recordings were measured with the devices CardioScreen 1000, CardioScreen 2000 and TensoScreen with the corresponding Software Cardiovascular Lab 2.5 (Medis Medizinische Messtechnik GmbH, Illmenau, Germany). In order to create identical frame conditions, all measurements were recorded in the same position and for the same duration. Various positions were simulated from horizontal lying position to vertical standing position. Altogether, more than 30 hemodynamic parameters were measured.
In contrast to conventional aortic valve replacement, the Transcatheter Aortic Valve Implantation (TAVI) is a new highly specialist alternative to surgical valve replacement for patients with symptomatic severe aortic stenosis and high operative risk. The procedure was performed in a minimally invasive way and was introduced at the university heart centre, Freiburg – Bad Krozingen in 2008. The results have been getting better and better over the years. The aim of the investigation is the analysis of electrocardiogram conduction time and the electrocardiography changes recorded hours and days after the procedure depending on artificial heart valve models, which may lead to pacemaker implantation, even the analysis of the effectiveness of treatment.
The present invention relates to open-loop and closed-loop control units for extracorporeal circulatory support, to systems comprising such an open-loop and closed-loop control unit, and to corresponding methods. An open-loop and closed-loop control unit (10) for extracorporeal circulatory support is proposed, which is configured to receive a measurement of an ECG signal (12) of a supported patient over a predefined period of time, wherein the ECG signal (12) comprises multiple data points for each time point within a heart cycle. The open-loop and closed-loop control unit (10) comprises an evaluation unit (100) which is configured to evaluate the data points for at least one time point in a spatial and/or temporal manner and to determine at least one amplitude change (14) within the heart cycle based on the evaluated data points. The open-loop and closed-loop control unit (10) is further configured to output an open-loop and/or closed-loop signal (16) for extracorporeal circulatory support at a predefined point in time after the at least one amplitude change (14).

The aim of the essay is to identify current trends in infrastructure financing in times of net zero, crucial challenges, and solutions to overcome these issues. To gain information, a fundamental literal research, and interviews with infrastructure financing specialists of development banks were conducted. The growing importance of climate aspects for financing decisions, the changing sources of infrastructure funding and the increased role of Multilateral Development Banks (MDBs) can be listed as the most important trends. The main challenges are the financing gap for infrastructure, the high investment risks and a lack of standards, and policies regarding climate neutrality. To overcome these challenges, innovative financing solutions and the merging of public and private funding have been identified as potential solutions.
This paper examines and evaluates the challenges and opportunities of export credit agencies (ECA) in the Middle East and North Africa (MENA) region. Political risks, unrest and instability made exports in the MENA region arduous. Further challenges are demonetization, the lack of reliable information and the acquisition of skilled employees. Access to financial resources can be quite challenging and several ECAs in the MENA region struggle from having no economies of scale. The global trend of globalisation and digitalisation has proved to be both a challenge and an opportunity. Nevertheless, the ECAs are becoming progressively important and needed in the MENA region. ECAs can benefit from this by working closely with financial institutions, banks and stakeholders. Other opportunities are infrastructure, renewable energies, international events and the diversification of the product portfolio. Through research on the ECAs EGE, ECI, Credit Oman and ICIEC, differences of multilateral and national export credit agencies have been analysed as well.
The aim of this essay is to point out the challenges and opportunities of government export credits and insurance in Europe. The Covid-19 pandemic confronted the entire world with new challenges. This also applied to the export financing and insurance market. Furthermore, there are also challenges that play a major role for ECAs regardless of the pandemic. However, the risks are also offset by opportunities that may enable European export credit agencies to prevail against international competition.
The focus of this essay is on the export credit agencies from Finland (Finnvera), Sweden (EKN) and Portugal (COSEC). As part of the European Union (EU) and the Organisation for Economic Co-operation and Development (OECD) the three ECAs share many fundamental similarities but in some points they may also distinguish from each other.
The aim of this essay is to give an overview about recent developments of the government innovation funds of Sweden and Finland. In order to discover recent developments basic knowledge regarding innovation funds, funding structures and information about the two big funding agencies Vinnova Sweden and Business Finland is presented. Building on this information, the developments of the two funding agencies are compared and examined for similarities and differences. Both countries have a very similar structure in terms of the R&D sector and are striving with the same issues. Just as sustainability is a leading issue, the collaboration between the different shareholders is another main challenge. Both topics were negatively affected by the COVID-19 pandemic. Both Sweden and Finland had to really push forward innovation with financial support and political, strategic goals. Even though there are strong recent developments, the countries are facing the same challenges, do have similar funding structures and therefore have no big comparative strengths or weaknesses to each other.
Innovation Policies and Government Instruments – An illustration of Israel’s innovation system
(2021)
The aim of this paper is to introduce innovation policy measures, government instruments and conceptual approaches to promote innovation growth. Since Israel is increasingly establishing itself as a pioneer for innovation, this paper mainly refers to their innovation policy. This paper will explain why Israel's innovation policy is successful and which actors play a particularly important role in it. Using semi-structured interviews, government experts like the Israel Innovation Authority as well as companies like Bosch were asked about Israel’s national innovation system and its success which allowed diverse perspectives on the topic.
The aim of this essay is to give a systematic review of the literature. Climate change is omnipresent and manifests itself in a steady increase in global warming. This trend was triggered as a reaction to increasing emissions in the course of industrialization. Climate finance is generally understood to be the provision of public, private, and alternative sources of finance that represent measures to mitigate and adapt to climate change. Significant commitments to support developing countries by developed countries have been manifested in the UNFCC climate framework and the Paris Climate Agreement. Funding from public and private sources increased to a total of $540 billion in 2019. Whether multilateral or bilateral, the largest share is provided in the form of loans to the target countries.
