Computational Contact Mechanics
Topics of this book span the range from spatial and temporal discretization techniques for contact and impact problems with small and finite deformations over investigations on the reliability of micromechanical contact models over emerging techniques for rolling contact mechanics to homogenization methods and multi-scale approaches in contact problems. Furthermore, solution algorithms for single- and multi-processor computing environments, enabling methods that span from multi-contact to multi-scale approaches are discussed together with numerical experiments related to soil mechanics using discontinuous deformation analysis.
Computational Contact Mechanics
This is the second edition of the valuable reference source for numerical simulations of contact mechanics suitable for many fields like civil engineering, car design, aeronautics, metal forming, or biomechanics. Boundary value problems involving contact are of great importance in industrial applications in engineering such as bearings, metal forming processes, rubber seals, drilling problems, crash analysis of cars, rolling contact between car tires and the road, cooling of electronic devices... Other applications are related to biomechanical engineering design where human joints, implants or teeth are of consideration. Due to this variety, contact problems are today combined either with large elastic or inelastic deformations including time dependent responses. Thermal coupling also might have to be considered. Even stability behaviour has to be linked to contact.
Combined and Hybrid Adsorbents : Fundamentals and Applications
Adsorption is a separation process playing a fundamental role in several industrial areas, being used in both purification and bulk separations. The adsorbent used is the main parameter controlling the effectiveness of the process. Emerging new separations and the improvement of existing ones constitute the driving force for the development of new adsorbents with improved adsorbing properties.
Materials Issues for Generation IV Systems ; Status, Open Questions and Challenges
Global warming, shortage of low-cost oil resources and the increasing demand for energy are currently controlling the world's economic expansion while often opposing desires for sustainable and peaceful development. In this context, atomic energy satisfactorily fulfills the criteria of low carbon gas production and high overall yield. However, in the absence of industrial fast-breeders the use of nuclear fuel is not optimal, and the production of high activity waste materials is at a maximum. These are the principal reasons for the development of a new, fourth generation of nuclear reactors, minimizing the undesirable side-effects of current nuclear energy production technology while increasing yields by increasing operation temperatures and opening the way for the industrial production of hydrogen through the decomposition of water.

Liver
Liver is the second largest organ in human body, more than 5,000 separate bodily functions including helping blood to clot, cleansing the blood of toxins to converting food into nutrients to control hormone levels, fighting infections and illness, regenerating back after injury and metabolizing cholesterol, glucose, iron and controlling their levels. Most people never give their liver a thought until something goes wrong, yet, liver diseases on rise, affecting one in ten. Liver diseases can be inherited or caused by a variety of factors that damage the liver.
Liquid separations with membranes : An introduction to barrier interference
On the level of a textbook a self-consistent approach to liquid separations with membranes is presented, contrasting equilibrium separations with the rate-controlling effects of barrier interference on mass transfer. As a corollary objective, an effort is made to observe context, factual and historical, when introducing concepts and applications of membrane separation science. Ordering principle is the formal structure of mass transfer across barriers, being construed of a driving force (allocated to the condition of the mixtures to be separated) and a barrier permeability (holding the keys to membrane selectivity). The membranes, by this approach, appear by way of the mass transport demands which they are to meet, or else by way of the separation effects which they inspire.

Key Account Management in Business-to-Business Markets: An Assessment of Its Economic Value
In times of fierce competition in business-to-business markets strong and economically sound business relationships with a company's customers rank among the main success factors. As a well established marketing management conception, key account management is of particular significance in this context. Interestingly enough, empirical research studies have recently proved that relationship marketing, and particularly key account management, does not achieve the economic value originally expected.

Cell Division Control in Plants
The molecular mechanisms controlling cell cycle progression are highly conserved in eukaryotes. In addition to the basic protein machinery involved in cell cycle regulation, higher plants have also evolved unique molecular mechanisms that allow integration of environmental, physiological, and developmental signals into networks to control proper cell division and expansion. Rapid and exciting research progress in these fields has been achieved from experimental observations on plants over the past decade. The scope of this volume is focused on the molecular basis of all aspects of cell division and cytokinesis in plants. It is an essential reference book for instructors and scientists working in the areas of molecular, cell, and developmental biology of plants. The editors of this book are veterans in the field of plant molecular biology and highly respected worldwide.
Bridging divides : Maritime canals as invasion corridors
Maritime canals dissolve natural barriers to the dispersal of marine organisms, thus providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. The introduction of alien species has proved to be one of the most profound and damaging of anthropogenic deeds - with both ecological and economic costs. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.
Brain thoughts recognition
Humans controlling machines with their minds may sound like something from a scifi movie, but it’s becoming a reality through brain-computer interfaces BCI. Where BCI technology allows a human brain and an external device to talk to each other—to exchange signals. It gives humans the ability to directly control machines, without the physical constraints of the body. There are two ways to implement the BCI: Noninvasive tools often use sensors applied on or near the head to track and record brain activity, or Invasive BCI would require surgery. Electronic devices would need to be implanted beneath the skull, directly into the brain, to target specific sets of neurons. In order to implement a non-invasive BCI in a mobile phone, this study developed a mobile application to help paralyzed people who do not have the ability to use their phones to spend their basic daily needs, such as using the keyboard and interacting with PDF, etc.
