Boron-doped diamond (BDD) electrodes offer some excellent electrochemical properties, including the widest potential window in aqueous solutions, low background currents and good chemical and mechanical stability. They can also be produced transparent and could offer a great potential for spectroelectrochemical (SEC) experiments. However, to reach the mentioned electrical properties for such optically transparent electrodes (OTE), heavy doping is needed to increase conductivity. The introduction of boron in return reduces the transparency significantly. This work investigates the effect of introducing an alternative path for electrons in the form of an highly conductive get transparent interlayer which could increase the conductivity without increasing the BDD film or the doping level supporting high transparency in the visible (Vis) and ultraviolet (UV) regime. This work furthermore investigates possible interlayers for this application and implements four of them in two BDD OTE samples which are extensively studied by electrical, optical and electrochemical methods. An ultra-thin metal film (UTMF) of titanium (Ti) is shown to decrease the electrochemical resistance by 2.4kOhms while decreasing the transparency of a BDD OTE by only 11%.
China is planning to rebuild the ancient Silk Road into a modern infrastructre network, spanning Asia, Central Asia and Europe. The investements are high and are not paying off. This thesis is exploring the political reasons for China's plans and the impact the initiative has on the Chinese-Kazakh relationship.
This bachelor thesis is about the development and design of the suture-based HeartStitch MR device for functional restoration of the mitral valve when a mitral regurgitation is present. The mitral valve is one of the four existing heart valves and due to their load, the mitral valve is most commonly affected by valve defects. In case of a mitral regurgitation, the leaflets of the mitral valve are not closing tight enough, which causes a reflux of the oxygenated blood from the left ventricle into the left atrium. As consequence, the human body won't be sufficiently supplied with oxygen anymore, which results in a disproportionate cardiac output. Untreated, this can lead to respiratory dis-tress, cardiac arrhythmias and stroke or even to death. In this case, a heart surgery is essential to improve the patient
Morality confronts us in our daily life. Sometimes people do not act the way we would have expected it. One of the biggest culture differences can be found between China and Germany. A lot of foreigners try to make business in the more and more economic important becoming country. A lot of them fail, because of not knowing how to act in certain circumstances. Furthermore, some situations are happening which one would not expected. Everyone got influenced by media about China. But is everything true about it? Most of the journalists are from western countries and they decide what is right and what wrong dependent from their origin. We call such a situation ethnocentrism. It means, that one judges dependent on ones ethnical norms one raised up with and that these norms are basis of valuation on other cultures (Schubert, 2011). While I was in China, I experienced a lot moral misunderstandings. I found out that especially foreign companies do have huge problems in that term because they use their - grown up morality- in China which is not working. This paper explains moral inequalities and helps companies to act differently in consideration of a very important topic such as payment morality.
Methods of analyzing the structural integrity of compound materials under stressed conditions becoming more importantly. Not merely safety and economic reasons demanding a good monitoring of e.g. wind turbine blades or aircraft wings but also ecological ones. The existing strategy for the blades is to replace them at a certain schedule, resulting in unnecessary downtimes and high cost. Several possibilities of an optical structural health monitoring system been examined in this thesis. Both free-space and fiber-based setups are tested and evaluated in their usability. The methods were tested with the objective of embedding them into large-scale polymer structures such as the mentioned fields of application.
This thesis will examine the process of internationalization which generates international changes and growth, entry into new markets and the creation of new businesses. Projecting this on the sports industry, businessmen tend to take more risks than a few decades ago in the interest of becoming more competitive. The sports industry is used to transmit multiple messages as it reaches global audiences. The term sports covers much more than the physical activity. The term also comprises possibilities for lucrative business actions, sponsoring and image creation. Furthermore, it induces a pooling of diverse cultures. Thanks to this boundary-spanning connection of sportsmen and arising opportunities to increase sales, managers have decided to go international and to expand their company
The leading question, which political system is better suited for an emerging economy with a large population to ensure an effective climate protection, builds the nucleus of this thesis. The People's Republic of China and the Republic of India, which share similar demographic conditions and represent an autocratic and a democratic form of government, are compared in terms of the formulation and implementation of climate protection strategies and measures to draw conclusions about the characteristics of the respective systems.
The NobleStitchTM EL Cardiovascular Suturing System can be used in general surgical, interventional and endoscopic procedures, such as Patent foramen ovale (PFO) closure, transapical ventricular closure, carotid arterial closure, mitral annuloplasty or edge-to-edge mitral valve repair. The System is used through an access device or in an open setting. For applying suture to a wound site, one Device of the NobleStitchTM EL Cardiovascular Suturing System, called the NobleStitchTM EL (S)
China has become one of the largest economies world wide. While China itself used to receive huge amounts of FDI or aid from developed countries, it is now in the position to support less developed coutries. Cambodia is an example for such an LDC which is strongly supported through development aid and investments from China. This thesis analyses the unique advantages this country is offering to China. In addition, this thesis is trying to evaluate whether both participating countries equally benefit from this partnership.
