Laser Sintering (LS) with plastics is one of the most promising additive manufacturing technologies: it is currently regarded as the process most likely in the future to permanently cross the border between prototyping and the production of functional parts. This step is challenging because it means that the technology must meet certain requirements that are also valid for traditional and established production processes. Only by succeeding at this step can a wide industry acceptance of LS be expected in the future. In this context, this book covers all levels of the LS process chain, including: - Current state of the machine technology - Essential process steps, both before and during sintering - Specific demands of the materials, powder production methods, and evaluation of powder properties - Mechanical properties and density of the parts produced by LS Examples of LS-produced parts are given, including those with special design features, to illustrate the characteristics and also the limitations of the LS method. In particular, the distinct advantages of LS parts over parts produced with other plastics processing methods (e.g., injection molding) are discussed--

This book addresses customized laser vision correction and integral management options for the treatment of irregular corneas. This type of treatment reshapes the corneal surface in order to improve both the quality and the quantity of vision by reducing high order aberrations. Beginning with an introduction to the basics of this science, the three types of customized laser vision correction are then discussed by experts in this field. Throughout this practical guide, clinical examples are supported with the most recent scientific material and a step-by-step systematic methodology to fit all levels of ophthalmologists. .

Flow cytometry's informative potential has been underestimated for many years because of a lack of adequate instruments, automation, reagents, and know-how to approach, integrate, and also substitute other techniques giving single information per assay. In the last decade, flow cytometers have become capable of performing high-throughput screening and high content analysis, evaluating tens of different samples' features in a single run up to 1536 formats on multiple cell populations. The introduction of imaging flow cytometry has filled the gap between flow cytometry and conventional high content imaging screening, putting flow cytometry at the center of many laboratories, which can now cover with a single instrument the vast majority of needs in research programs. The flow cytometry community is a multidisciplinary and diversified group with many different interests and fields of action. These characteristics have prompted the evolution of the techniques, applications, and instruments that allow the use of complex, sophisticated, and standardized and reliable flow cytometric assays in academic and industrial programs.

Probing and controlling electrons and nuclei in matter at the attosecond timescale became possible with the generation of attosecond pulses by few-cycle intense lasers, and has revolutionized our understanding of atomic structure and molecular processes. This book provides an intuitive approach to this emerging field, utilizing simplified models to develop a clear understanding of how matter interacts with attosecond pulses of light. An introductory chapter outlines the structure of atoms and molecules and the properties of a focused laser beam. Detailed discussion of the fundamental theory of attosecond and strong-field physics follows, including the molecular tunnelling ionization model (MO-ADK theory), the quantitative rescattering (QRS) model, and the laser induced electronic diffraction (LIED) theory for probing the change of atomic configurations in a molecule. Highlighting the cutting-edge developments in attosecond and strong field physics, and identifying future opportunities and challenges, this self-contained text is invaluable for students and researchers in the field.

Flow cytometry allows for the measurement of different aspects of a cell or particles in real time. Applications include quantifying various types of T cells to determine the presence of various immune disorders, such as whether HIV has progressed to AIDS, studying the dynamics of immune signaling in cells to detect the suppression of normal immune function, and analyzing biopsy specimens for tumors, to aid in cancer diagnosis and prognosis. In addition to simplifying the technique and using vocabulary accessible to those not trained in cell biology and immunology, the book includes the following 4 unqiue features: 1) Tips on how to set up an experiment for flow cytometry optimially 2) An expanded data set of flow staining including multiparameter flow cytometry 3) Detailed staining protocols for flow cytometry (ex. protocols optimized for transcription factors, secreted cytokines, phospho-antibodies, and surface antigens) 4) Section devoted to antibody development and conjugation.
