A critical parameter in any hyperthermia system is the SAR (specific absorption rate) pattern, which gives information about the energy absorption in the tumor and surrounding tissue. In this paper, we compare the ...

Electromagnetic fields can obviously hurt living organisms if the strengths are great enough. We discuss the application of FDTD to computation of electromagnetic energy absorption by a human body. In particular, we are concerned with evaluating the specific absorption rate (SAR) in the different human tissues and organs given the EM environment to which the body is exposed.

  • Case Studies

    This chapter explores a miscellany of subjects and provides a short historical context, contemporary methods that are now being used, visual cross‐overs and comparisons and suggestions for further reading. The case studies demonstrate a survey of printing and reproduction methods used in the past and how many have evolved over time. The chapter also explores the ideas, traditional processes and materials that may have been modified or recycled in response to emerging technologies and trends. The reason for including a case study on wallcovering, is that, like the traditional print, it demonstrates several centuries of provenance, and through print archives and picture books, highlights 2.5dimensional (2.5D) printings as applied design and art form. Advances in 2.5D and three‐dimensional (3D) printing also allow the production of accurate three‐dimensional physical models. The research also looks to develop accompanying software and data representation to produce a cohesive workflow toward future 2.5D printing technology and its creative applications.

  • The Facilitation of Hands‐On Learning

    Many employees have taken classes designed to improve their presentation skills. Continuing to improve those skills will certainly increase their ability to teach others. More importantly, however, is the ability to facilitate training. Generally, facilitation requires a smaller, more intimate audience, and necessitates significantly more student engagement. Facilitating skills are as important to a trainer as closing skills are to a salesperson. Understanding and advocating the value is one of the best things instructors can do as a leader. This chapter discusses a few specific things to complete the product experts facilitate learning more effectively. The only way to get better at a facilitating skill is to practice that skill. However, practice does not make perfect, in spite of what trainer may have heard in the past. When instructors must travel to teach a class, allow them the time necessary to be effective.

  • Optical Channel Effects

    This chapter discusses methodological approaches for the synthesis and purification of hydrophobic peptides and proteins and strategies, which allow the assembly of larger membrane proteins. One important aspect of the chemical synthesis of membrane proteins in order to study their functional properties necessitates their refolding into lipid membranes or solubilization in detergents. Intensive research has been continuing on the mechanism of membrane protein folding. The chapter presents three illustrative examples of successful syntheses of membrane proteins. Diacylglycerol kinase (DAGK) is a homotrimeric membrane‐embedded enzyme that catalyzes phosphorylation of diacylglycerol to form phosphatidic acid. The halobacterial transducer of rhodopsin (NpHtrII) forms a 2:2 complex with sensory rhodopsin (NpSRII). Light activation of this receptor leads to an activation of a downstream His kinase. In the third example, the power of the chemical synthesis of proteins is used for elucidation of cation specificity of the potassium channel KcsA.

  • IONOSPHERIC PROPAGATION

    The amplitude variations of a signal propagating through the ionosphere result from the destructive and constructive interaction of the signal phase resulting from the numerous signal paths through the nonhomogeneous medium; this phenomenon is referred to as scintillation. Signal propagation through the ionosphere is characterized by the refractive index. The refractive index and its influence on the various aspects of a received signal is the subject of this chapter. The chapter characterizes the electron densities in the ionosphere for the natural and nuclear‐disturbed environments and discusses the influence of the electron densities on signal propagation in terms of the refractive index. Application of the index of refraction to a communication link yields the influence of the ionospheric propagation on the received signal. The chapter concludes with a case study of a scintillation scenario using a differentially coherent modulation with interleaving and combining.

  • Laser Fundamentals

    This chapter presents an overview of the operational basics of lasers and the properties and characteristic parameters that define a laser system as well as the major types that are less or more commonly used in the military domain. It discusses the operational principle of a laser and associated topics such as two‐level laser, three‐level laser and four‐level laser, different parts that make up a laser system and modes of a laser. All particles, big or small, according to the basic rules of quantum mechanics, have discrete energy levels or states. A typical laser comprises of three main parts; namely the active medium, the pumping source and the resonant structure. Monochromaticity is one of the essential requirements for the laser radiation to be coherent. Coherence is the most important property that distinguishes the laser radiation from the ordinary light. The directionality of laser radiation has its origin in the coherence of the stimulated emission process.
