Role of the right and left parts of the heart in mechanisms of body adaptation to the conditions of long term space flight according to longitudinal ballistocardiography

The early and long-term development of promising young athletes is a decisive factor in being internationally competitive in top-level sports. Among the multitude of talent criteria suggested in the literature, motivation plays a prominent role in the area of psychological characteristics. It is recognised in practice and research as a relevant criterion for performance development across all sports. This article provides an overview of the current state of talent research in the field of motivation. First, the most common theories of motivation in competitive sports are described, then different measurement methods and their advantages and disadvantages as well as the predictive value of motivation for athletic performance are discussed. Finally, implications for practice are suggested. It can be summarised that motivation in sport is conceptualised and operationalised in different ways and that the decision for the right measurement instrument depends on the goal of the assessment. To get a comprehensive picture of an athlete’s motivational status, it is useful to assess several aspects of motivation through different methods.

This chapter discusses the topic of standards for Virtual Worlds with emphasis on their usability as a stable and reliable basis for long-term investments into 3D-E-Commerce. The text explains why standards are important for the success of Virtual Worlds as well as the business in these shared online 3D environments, and what the relevant criteria are to decide for the right technology and/or provider. Although sometimes in the shadow of popular proprietary platforms there are already many different candidates for a Virtual World standard, currently in different states of development. By choosing a 3D platform, E-Commerce providers will decide about their business potential and at the same time strengthen one or another standard in the current technical competition phase. So it is important to get an overview about the current approaches, their advantages and disadvantages as well as the tendencies for the future developments. In this chapter the reader will be sensitized for the issues of standardization, compatibility and interoperability of Virtual Worlds for successful E-Commerce applications. An overview about the current approaches supports the orientation and decision for the different technologies. Some concrete XML-based code examples realized in the international ISO standard for interactive 3D-Graphics X3D demonstrates the practical deployment of highly compatible concepts. An outlook to the further integration of interactive 3D graphics into the Next Generation Web respectively the 3D Internet completes the overview.

The Right

Peptic oesophageal stricture can be considered as the end result of prolonged gastro-oesophageal reflux. The ‘gold standard’ treatment for peptic stricture is endoscopic dilatation with balloon or bougie. It is predicted that up to 40% of patients remain symptomatic with dysphagia due to refractory (resistant to treatment) or recurrent strictures, needing frequent interventions at short intervals. Such patients have poor nutritional status due to the primary disease and are susceptible to complications related to repeated endoscopic dilatation such as bleeding and perforation. This general review aims to analyse existing published evidence and address the role of biodegradable stents in resistant peptic strictures as an alternative treatment to provide long-term dysphagia-free intervals.
