The purpose of this book is to bridge the gap between the traditional Geomechanics and Numerical Geotechnical Modelling with applications in science and practice. Geomechanics is rarely taught within the rigorous context of Continuum Mechanics and Thermodynamics, while when it comes to Numerical Modelling, commercially available finite elements or finite differences software utilize constitutive relationships within the rigorous framework. As a result, young scientists and engineers have to learn the challenging subject of constitutive modelling from a program manual and often end up with using unrealistic models which violate the Laws of Thermodynamics. The book is introductory, by no means does it claim any completeness and state of the art in such a dynamically developing field as numerical and constitutive modelling of soils. The author gives basic understanding of conventional continuum mechanics approaches to constitutive modelling, which can serve as a foundation for exploring more advanced theories. A considerable effort has been invested here into the clarity and brevity of the presentation. A special feature of this book is in exploring thermomechanical consistency of all presented constitutive models in a simple and systematic manner.

This book investigates geopolymers and geopolymer-based composites, with a focus on their preparation, geopolymerization mechanisms, microstructures, mechanical properties, and fracture behaviors. Geopolymers are inorganic materials consisting of tetrahedral units (such as [SiO4] and [AlO4]) linked by shared oxygens and forming long-range, covalently bonded and amorphous frameworks. Geopolymers have the advantages of low-temperature preparation, low cost, high heat and corrosion resistance, and being environmentally friendly. Using the preparation methods for epoxy-based composite, they can easily be formed into complex shapes or structures. Intended for researchers investigating geopolymers and their matrix composite materials, this book is also a valuable resource for engineers from various fields, such as materials, mechanical, civil and structural engineering, as well as students interested in other kinds of inorganic materials or even cementitious materials in general.

This volume contains the proceedings of the 5th International Symposium on Symmetries in Subatomic Physics (SSP2012), that was held in Groningen, The Netherlands from 18 till 22 June 2012. This sequence of symposia is now firmly connected with one of the main branches in fundamental nuclear and particle physics, i.e. in searches for physics beyond the Standard Model, focused on the (violation of) the discrete symmetries of Parity, Charge conjugation and Time reversal invariance. This field comes in various disguises: With large experimental facilities and large collaborations, as in LHC physics or in neutrino experiments, but also as table top experiments by small groups in the field of nuclear, atomic and molecular physics, such as in searches for a permanent electric dipole moments and atomic parity violation.

Bringing the practitioners of these divergent fields together gives a coherent overview and see the complementarities of the various approaches to the same question: why is the Standard Model what it is and what lies beyond it.

This thesis introduces a series of novel, non-conjugated polyarylether hosts that are not subject to the triplet-energy limitations of traditional conjugated polymer hosts. As a result of this major breakthrough, the long-standing problem of triplet energy back transfer has now been overcome, making it possible to design high-efficiency electrophosphorescent polymers (PhPs), especially the blue and all-phosphorescent white ones. In addition, the author proposes a spiro-linked hyperbranched architecture for PhPs to inhibit the undesired triplet energy back transfer process in low triplet-energy hosts. The work in this thesis provides vital new insights into the design of PhPs and has led to several publications in high-profile journals.

This book presents the main outcomes of the first European research project on the seismic behavior of adjustable steel storage pallet racking systems. In particular, it describes a comprehensive and unique set of full-scale tests designed to assess such behavior. The tests performed include cyclic tests of full-scale rack components, namely beam-to-upright connections and column base connections; static and dynamic tests to assess the friction factor between pallets and rack beams; full-scale pushover and pseudodynamic tests of storage racks in down-aisle and cross-aisle directions; and full-scale dynamic tests on two-bay, three-level rack models. The implications of the findings of this extensive testing regime on the seismic behavior of racking systems are discussed in detail, highlighting e.g. the confirmation that under severe dynamic conditions "sliding" is the main factor influencing rack response. This work was conceived during the development of the SEISRACKS project. Its outcomes will contribute significantly to increasing our knowledge of the structural behavior of racks under earthquake conditions and should inform future rack design.

This book provides a line of communication between academia and end users/practitioners to advance forensic science and boost its contribution to criminal investigations and court cases. By covering the state of the art of promising technologies for the analysis of trace evidence using a controlled vocabulary, this book targets the forensics community as well as, crucially, informing the end users on novel and potential forensic opportunities for the fight against crime. By reporting end users commentaries at the end of each chapter, the relevant academic community is provided with clear indications on where to direct further technological developments in order to meet the law requirements for operational deployment, as well as the specific needs of the end users. Promising chemistry based technologies and analytical techniques as well as techniques that have already shown to various degrees an operational character are covered. The majority of the techniques covered have imaging capabilities, that is the ability to visualize the distribution of the target molecules within the trace evidence recovered. This feature enhances intelligibility of the information making it also accessible to a lay audience such as that typically found with a court jury. Trace evidence discussed in this book include fingermarks, bodily fluids, hair, gunshot residues, soil, ink and questioned documents thus covering a wide range of possible evidence recovered at crime scenes.

This book mainly focuses on the theoretical and experimental study of non-Fourier heat conduction behavior. A novel thermomass theory is used as the theoretical basis, which provides a general heat conduction equation for the accurate prediction of non-Fourier heat conduction. In order to prove the validity of this thermomass theory, a large current was used to heat the metallic nanofilm at the minimum temperature of 3 K. The measured average temperature of the nanofilm was notably higher than the prediction of Fourier's heat diffusion equation, while matching well with the general heat conduction equation. This is the first time that steady non-Fourier heat conduction has been observed. Moreover, this book concerns the role of electron-phonon interaction in metallic nanofilms, which involves the breakdown of the Wiedemann-Franz law at low temperatures and interfacial thermal resistance at femtosecond timescales. Readers will find useful information on non-Fourier heat conduction and the latest advances in the study of charge and heat transport in metallic nanofilms.
