Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The gas turbine doubtlessly is one of the most important modern machines to convert energy from heat to power, and improving its efficiency is a ceaseless task. The most practical route to increase the efficiency is to increase the maximum operating temperature. Over the past several decades, the improvement of this temperature was constantly attained by the developments of thermal barrier coating and superalloys, but almost reached a limit because the microstructural deterioration of both the base superalloy and the coating system due to the interdiffusion between them can be dramatically aggravated by further increasing temperature. The novel diffusion barrier type bond coat, therefore, is a solution to this issue. This book introduces how to form a rhenium-based diffusion barrier on a nickel-based superalloy. The formation process and thermal stability of the diffusion barrier are discussed through analyzing its macro- and micro-structures by XRD, EBSD, EPMA, SEM, and TEM, etc. This work provides the fundamental knowledge about the novel coating system, and should be especially useful to researchers and students in high-temperature materials science and technology. 204 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an early attempt to investigate entrepreneurial practices of second-generation family entrepreneurs in Hong Kong and Mainland China. A group of management scholars have marshalled theoretical and empirical evidence to support their proposition that entrepreneurial practices of family entrepreneurs in Diaspora and Mainland Chinese societies are due mainly to the influence of Confucianism. Based on the Weberian premise that culture can enhance levels of entrepreneurial activity and reinforce entrepreneurial practices, the culturist perspective maintains that entrepreneurial practices of family entrepreneurs can be interpreted as a fixed essentialised cultural phenomenon. This book provides evidence against the culturist perspective that Chinese family entrepreneurs are passive recipients of traditional cultural values as fundamental changes in entrepreneurial practices have been found. Therefore, the extant culturist perspective should be refined and reinterpreted judiciously. The research findings shed some light on the understanding of Chinese entrepreneurial practices, and are useful to scholars and professionals in the field of family business. 328 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The highest rates of child mortality are still in the sub-Saharan Africa, where 1 in 8 children dies before the age of five. The leading causes of morbidity and mortality in children particularly in Sub-Saharan Africa are infectious diseases of which fever is a common feature. More importantly, is the fact that Nigeria is an endemic zone for malaria. For decades, fever had served as the entry point for presumptive treatment of malaria in African children, who if left untreated run the risk of severe complications and death. Decisions about whether to take action and which actions to take are often based on a lot of factors and not necessarily on scientific data. Early diagnosis and prompt treatment of fever has been the cornerstone of malaria control but this depends on the early recognition of the disease, and subsequently the health-seeking behaviour of the child s mother/caregiver. 104 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Embryo-toxic effects of lead nitrate of the African catfish with different modes of action were determined. Exposure of fertilized eggs to lead nitrate prolonged the incubation period and caused severe malformations. No specific response in the activities of the selected enzymes and no extremely DNA damaged was recorded in the pre-hatching stage exposed to the lead nitrate doses. In contrast, remarkable alterations in the activities of the same enzymes and significant dose-related DNA damage response over time in the post-hatching stages were recorded. Low susceptibility in pre-hatching stages is most probably a consequence of the chorion, which seems to protect the embryos from a range of external pollutants. In addition, histopathological malformations confirmed a decreased sensitivity in pre-hatching stages: The degree of malformations in the eyes, gills and notochord increased drastically after hatching. In our point of view, the protective capacity provided by a hardened chorion is a very interesting finding, well worth further studies. The selected biomarkers were sensitive detection methods for low-level toxicity of lead nitrate. 136 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Aerospace is very important to the Canadian economy, with over 80,000 employees; generating over $20 billion dollars in revenue. However, with the economic downturn, sales have been decreasing. Competition is growing with emerging countries entering the market, companies are struggling to stay competitive, and they are adopting various practices to deliver value to their customers. The principles of lean manufacturing strive to do just that, and while enjoying much success in production environments, lean principles have been found to be applicable in other areas of the enterprise, including accounting. This study presents the notion of target costing for new products. In comparison to traditional costing of products, where the desired profit is added to the cost required to develop the product, target costing is lean in the sense that it puts the focus on creating value for the customer by setting the price of the product based on the cost. In this book, various types of target cost models are developed. The models are then applied to predict the cost of commodities at a major Canadian aerospace company. 180 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Do religions change Anyone raised in a religion sees this tradition as one set in stone. This study shows the opposite, thus it focuses on the metamorphoses of the religious showing religions as complex and dynamic systems of change. The religious begins with the existential openness to the universe as a system. This is a natural ability of the mind to sense an unseen reality as the unlimited semiosis such as God, the supreme, or spirits. The author defines religious experience as the semiotic space. This inner space often challenges orthodoxy or orthopraxy bringing changes. The best known example is the Western epoch of modernity, where the semantic ethical and aesthetic religious potentials have been transformed from the religious into the secular sphere. The Semiotic Theory of Religion based on semiotics of Charles Sanders Peirce, Umberto Eco, Yuri Lotman, and the communicative evolution theory of Jürgen Habermas explains the secularization processes of the religious and their effects on politics, arts, and spirituality. The Semiotic Theory of Religion posits a view on religion as one of the most dynamic socio-cultural sub-systems of change within the Semiosphere. 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Double oxide films are significant defects in aluminium castings which were reported to have a detrimental effect on the reliability of the castings. This book reported the results of a research which was aimed at studying the behaviour of these defects in the liquid metal once they have formed. The results suggested that both oxygen and nitrogen inside the bifilm would be consumed by reaction with the surrounding melt, and that hydrogen might be diffused into the defect. The time required for the consumption of the atmosphere inside a defect entrained in pure Al, Al-7Si-0.3Mg and Al-5Mg alloy melt, was determined to be 9, 25 and 6 minutes respectively. In addition, the results suggested the occurrence of two competing mechanisms during holding of the castings in the liquid state before solidification. The consumption of air inside the defects due to reaction with the surrounding molten metal may lead to improvements in mechanical properties, but this may be accompanied by hydrogen passing into the defects, which has a deleterious effect on properties. This research could lead to the development of new techniques by which these defects might be deactivated in aluminium castings. 332 pp. Englisch.
