What does it mean to be an entrepreneurial scholar? Dimo Dimov draws on an eclectic range of philosophical ideas to investigate the study of entrepreneurs and makes the case for entrepreneurial scholarship to become more holistic, dynamic, and future oriented. This thought-provoking book argues that entrepreneurs seek to put knowledge in the service of the future, whereas scholars seek to put the future in the service of knowledge. Engaging with this tension, Dimov explores the relationship between the study of entrepreneurship and the entrepreneurs who are studied. Creating a framework for entrepreneurial scholarship, this concise book highlights four distinct styles and approaches to the field: theoretical, integrative, craft and clinical. He invites reflection on the role and place of entrepreneurs in modern society, and puts the case that the entrepreneurial scholar should embrace interdisciplinarity as a way of engaging with entrepreneurship as a holistic experience, and draw on design science as a way of improving the art and skills of entrepreneurship. This innovative book will be a stimulating read for academics and students of entrepreneurship, and its accessible format will also appeal to reflective practitioners.

Chemistry and Application of H-Phosphonates is an excellent source for those planning the synthesis of new phosphorus-containing compounds and in particular derivatives containing a phosphonate, phosphoramide or phosphonic acid diester group. The rich chemistry, low cost and easy availability of diesters of H-phosphonic acid makes them an excellent choice as synthone in a number of practically important reactions.

Phosphonic acid esters are intermediates in the synthesis of important classes of compounds such as alpha-aminophosphonic acids, bisphosphonates, epoxyalkylphosphonates, alpha-hydroxyalkylphosphonates, phosphoramides, poly(alkylene H-phosphonate)s, poly(alkylene phosphate)s, nucleoside H-phosphonates. The synthesis of each of these compound classes is reviewed in detail.

Alpha-Aminophosphonic acids are an important class of biologically active compounds, which have received an increasing amount of attention because they are considered to be structural analogues of the corresponding Alpha-amino acids. The utilities of alpha-aminophosphonates as peptide mimics, haptens of catalytic antibodies, enzyme inhibitors, inhibitors of cancers, tumours, viruses, antibiotics and pharmacologic agents are well documented. Alpha-Hydroxyalkanephosphonates are compounds of significant biological and medicinal applications. Dialkyl epoxyalkylphosphonates are of interest because of their use as intermediates in the synthesis of bioactive substances, and as modifiers of natural and synthetic polymers. Bisphosphonates are drugs that have been widely used in different bone diseases, and have recently been used successfully against many parasites. Poly(alkylene H-phosphonate)s andpoly(alkylene phosphate)s are promising, biodegradable, water soluble, new polymer-carriers of drugs. Nucleoside H-phosphonates seem to be the most attractive candidates as starting materials in the chemical synthesis of DNA and RNA fragments. The 5'-hydrogen phosphonate-3'-azido-2',3'-dideoxythimidine is one of the most significant anti-HIV prodrug, which is currently in clinical trials.

Chapters review the synthesis; physical and spectral properties (1H, 13C, 31P and 17O NMR data); characteristic reactions; important classes of compounds based on these esters of H-phosphonic acid; their application as physiologically active substances, flame retardants, catalysts, heat and light stabilizers, lubricants, scale inhibitors, polymer-carriers of drugs; preparation of H-phosphonate diesters and general procedures for conducting the most important reactions.

Among the major ways researchers think about research topics and approaches, the lesson of these ten chapters by many of the new breed of European entrepreneurship researchers is that those values and world-views which have traditionally been the hallmark of the European approach, remain evident as the underpinnings of the new breed approach. In doing so, the field of entrepreneurship will grow in terms of the range of ideas, data sources, and techniques. It will also grow more competitive, initially through the addition of new people, but as their ideas begin to gain traction, as differing worldviews and approaches come to the fore, and perhaps sometimes into conflict. However, that sort of exchange, one which broadens each participant, is what science and academia is all about, and the new breed, through efforts such as the volume you are holding, are working to initiate that process.

In a world where entrepreneurial success often seems deceptively accessible, it is not always clear what makes a person entrepreneurial. In this book, Dimo Dimov offers a reflective insight into the entrepreneurial journey, striking up a conversation about entrepreneurship in order to challenge and untangle existing preconceptions. A discussion of challenges and tensions such as idea versus opportunity, genius versus lunatic, and skill versus luck forms the foundation of the book, while the second part offers actions and considerations which can help the reader to seek opportunities in a fractious environment. The final part of the text focuses on the collective spirit in entrepreneurship, arising from the interplay between participation and outcomes. The author brings a succinct diversity to the field, making this book essential reading for undergraduate and postgraduate students on entrepreneurship courses, as well as scholars, researchers, and practitioners looking for a new perspective on entrepreneurship.

The book serves as a synergistic link between the development of mathematical models and the emergence of stochastic (Monte Carlo) methods applied for the simulation of current transport in electronic devices. Regarding the models, the historical evolution path, beginning from the classical charge carrier transport models for microelectronics to current quantum-based nanoelectronics, is explicatively followed. Accordingly, the solution methods are elucidated from the early phenomenological single particle algorithms applicable for stationary homogeneous physical conditions up to the complex algorithms required for quantum transport, based on particle generation and annihilation. The book fills the gap between monographs focusing on the development of the theory and the physical aspects of models, their application, and their solution methods and monographs dealing with the purely theoretical approaches for finding stochastic solutions of Fredholm integral equations.

Rapid Manufacturing is a term that embraces rapid prototyping and rapid tooling.
Rapid prototyping is an exciting new technology for quickly creating physical models and functional prototypes directly from CAD models. Rapid tooling generally concerns the production of tooling using parts manufactured by rapid prototyping. Rapid prototyping and rapid tooling are means for compressing the time-to-market of products and, as such are competitiveness enhancing technologies.
The book describes the characteristics and capabilities of the main known rapid prototyping processes.
It covers in detail commercially available processes, such as:
- Stereolithography (SLA);
- Selective Laser Sintering (SLS);
- Fused Deposition Modelling (FDM);
- Solid Ground Curing (SGC);
- Laminated Object Manufacturing (LOM)
and provides information on several other processes still under development.
The book discusses various direct and indirect methods of producing soft tooling, firm tooling (or bridge tooling) and hard tooling based on rapid prototyping. The discussion is wide- ranging and not found in other books published to-date. Also special to the book is material on process optimisation. This was derived from work at the authors'Centre and is not available in other texts. The book places a strong emphasis on practical applications, devoting special chapters to both the applications of rapid prototyping and rapid tooling. The book contains an abundance of photographs and diagrams, some in colour, to illustrate clearly the principles of the machines and processes involved. The book does not require any special background. It should be of interest to manufacturing, industrial, production, mechanical and materials engineers wishing to up date themselves on some of the most important developments in modern manufacture. (The authors are from the Manufacturing Engineering Centre, which conducts leading-edge research into advanced manufacturing as well as providing a commercial rapid prototyping and tooling service to several hundred industrial customers).
