  • This introduction to nuclear physics provides an excellent basis for a core undergraduate course in this area. The authors show how simple models can provide an understanding of the properties of nuclei, both in their ground and excited states, and of the nature of nuclear reactions. They include chapters on nuclear fission, its application in nuclear power reactors, the role of nuclear physics in energy production and nucleosynthesis in stars.

  • Because of their apparent “simplicity” simple atoms present a great challenge and temptation to experts in various branches of physics from fundamental problems of particle physics to astrophysics, applied physics and metrology. This book is based on the presentations at the International Conference on Precision Physics of Simple Atomic Systems (PSAS 2002) whose primary target was to provide an effective exchange between physicists from different fields.

  • This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable sophistication of nuclear medicine instrumentation and increase in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of nuclear imaging for diagnosis and therapy has origins dating back almost to the pioneering work of Dr G.

  • According to classical physics the particle cannot be a wave, and the wave cannot be a particle. However, Einstein, while explaining the photoelectric effect (PEE), postulated that electromagnetic radiation has a dual wave-particle nature. He used the term photon to refer to the particle of electromagnetic radiation. He proposed a simple equation to relate the energy of the photon E to the frequency n and wavelength l of electromagnetic wave.

  • The 20th century brought us the birth of the atomic age, with Albert Einstein’s understanding that E = MC2 in 1905, Ernest Rutherford’s theory of the structure of the atom in 1911, and the first sustained nuclear reaction in Chicago in 1942. While it brought the promise of a robust use of nuclear technologies for peaceful purposes, it also brought the reality of nuclear weapons in 1945. Those initial weapons were large, heavy, and complex to make and use. Moreover, only nations had nuclear weapons, not individuals or groups.

  • In an era of spectacular medical advances, it is easy to become immune to the announcement of new “breakthroughs”. This in no way lessens the remarkable achievements of diagnostic imaging over the last few years in which the field of Nuclear Medicine has shared. To the outsider the specialty of Nuclear Medicine can appear confusing and esoteric since it operates in a world of invisible radioactive emissions, nuclear decay charts and obscure elements.

  • Fenton's Reagent requires soluble Fe2+ to form OH•. This optimal reaction occurs under relatively low pH conditions (e.g., pH of 2 to 4). pH adjustment in the treatment area is often necessary to enable the oxidation process to proceed efficiently. This can be accomplished by either acidifying the hydrogen peroxide or by adding a chelating acid. Using a ferrous sulfate solution `simultaneously adjusts aquifer pH and adds the iron catalyst needed for Fenton's Reagent.

  • Quantum Field Theory is now well recognized as a powerful tool not only in Particle Physics but also in Nuclear Physics, Condensed Matter Physics, Solid State Physics and even in Mathematics. In this book some current applications of Quantum Field Theory to those areas of modern physics and mathematics are collected, in order to offer a deeper understanding of known facts and unsolved problems.

  • The book "Applied Fracture Mechanics" presents a collection of articles on application of fracture mechanics methods to materials science, medicine, and engineering. In thirteen chapters, a wide range of topics is discussed, including strength of biological tissues, safety of nuclear reactor components, fatigue effects in pipelines, environmental effects on fracture among others. In addition, the book presents mathematical and computational methods underlying the fracture mechanics applications, and also developments in statistical modeling of fatigue.

  • In the most common frequency AE used for testing, 100-300kHz, the AE sensor can detect a signal for surface movement of 10-13 m or less than one thousand times smaller than the size of an atom. As a monitoring device for structural integrity, acoustic sensors are more effective distance from a few tens of feet. It can be compared with the accelerations commonly used to assess the condition of the bridge, for example, through the techniques of method analyzed.

  • Microelectromechanical systems (MEMS) have played an increasingly important role in sensor and actuator applications. And its key contribution is that it has enabled the integration of multi-components (i.e., electronics, mechanics, fluidics and etc) on a single chip and their integration has positive effects upon performance, reliability and cost. Compared to conventional electrostatic, thermal or magnetic actuating schemes, piezoelectric MEMS inkjet has the advantages of lower power consumption, lower voltage operation and relatively larger driving force....

  • Cerium, an element in the lanthanide series, has a number of radioactive isotopes. Several of these are produced in abundance in nuclear fission reactions associated with nuclear industry operations or detonation of nuclear devices. This report summarizes our present knowledge of the relevant physical, chemical, and biological properties of radiocerium as a basis for establishing radiation protection guidelines.

  • The concept of tissue engineering is to regenerate target tissue by mimicking the developmental or regenerative process of that tissue. Thus, it can be considered an ideal therapeutic option for treating various tissue defects. Tissue engineering of skin, cartilage, and bone has already been shown both feasible and effective in several clinical studies, and its efficacy has attracted significant attention from both patients and doctors.

  • The hypotheses of this work are that in future there will be a clear demand for non-wood-based fibres at least in China and that the combined production of fibres and energy is more cost effective than the production of energy alone. In actual fact, no satisfactory process exists which could solve all of the traditional problems related to non-wood pulping.

  • There is no unique definition among investors of what green investing entails. However, for the purpose of this paper, „green‟ investments refer broadly to low carbon and climate resilient investments made in companies, projects and financial instruments that operate primarily in the renewable energy, clean technology, environmental technology or sustainability related markets as well as those investments that are climate change specific.

  • The other extreme is “monetary dominance”. Central banks raise interest rates to avoid the inflationary effects of excessive budget deficits. Real interest rates rise across the maturity spectrum and the prospect of higher-and-higher debt service costs then forces governments to reduce their primary deficits. This seems to fit the UK story in the late 1980s and early 1990s when tighter macroeconomic policies (monetary and fiscal) brought down inflation.
