  • The paper explores the target genres, determines the specificity of writing competences covered within the course, and then develops a competence-based course schedule. Since this is the first attempt of its kind, the paper is expected not only to present a needed course for the engineers at VAEI but also to provide suggestions for course design and its implementation in the light of Competence-based Approach.

  • The atomic absorption spectrometry uses absorption of light of intrinsic wavelengths by atoms. All atoms are classified into those having low energies and those having high energies. The state having low energies is called the ground state and the state having high energies is called the excited state. The atom in the ground state absorbs external energies and is put in the excited state. For example, sodium is mainly in two excited states, having higher energies by 2.2eV and 3.6eV respectively than in the ground state, as shown in Fig. 1.1.

  • This study was motivated by a conflict between the nonproliferation objectives of the Energy Policy Act of 1992, which created increasing pressures to phase out U.S. exports of highly enriched uranium (HEU) for medical isotope production, and the Energy Policy Act of 2005, which sought to increase the reliability of medical isotope supply by lifting the requirements of the 1992 Act for HEU exports to Canada, the Netherlands, Belgium, France, and Germany for medical isotope production.

  • An important trend identified by many workshop participants is that Russia and the United States are continuing the transition from an assistance relationship, which was prevalent during the 1990s, to a partnership relationship. A partnership relationship implies that the two countries are willing to share in setting priorities for cooperation, managing projects, and funding cooperative efforts.

  • The United States program of development of atomic energy has been described by Major General L. R. Groves, who, as Commanding General of the War Department's Manhattan Project, directed the program from mid-1942 until December 31, 1946, as "a generation of scientific development compressed into three years.

  • Thyroid cancers are now being diagnosed at an earlier stage and treatments together with follow-up strategies are more effective. However this is not consistent throughout the world. The practice does differ considerably from country to country and region to region. Many International Atomic Energy Agency (IAEA) Members States can benefit from the lessons learned and improve overall patient management of thyroid cancers. The IAEA has significantly enhanced the capabilities of many Member States in the field of nuclear medicine.

  • Recent advents in laser technology and discoveries in laser physics have enabled their very new and exciting applications. Some of them cover production of new materials: nano-particles, periodic structures in nano-scale, and thin films. Others allowed better understanding of laser-matter interaction when sample is subjected to intense laser pulses of various time duration, shape in space and time domains as well as different spectral components contained in a pulse.

  • Physical properties of metals, ceramics, and polymers, such as ductility, thermal expansion, heat capacity, elastic modulus, electrical conductivity, and dielectric and magnetic properties, are a direct result of the structure and bonding of the atoms and ions in the material. An understanding of the origin of the differences in these properties is of great engineering importance.

  • Generally, biomass is used for all materials originating from photosynthesis. In other words, biomass includes all plant growth, herbaceous plants, microalgae, macroalgae and aquatic plants. But biomass can equally apply to animal as well. In fact, biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen, usually including atoms of oxygen, often nitrogen and also small quantities of other atoms, including alkali, alkaline earth and heavy metals.

  • The U.S. legal system is admired around the world for the freedoms it allows the individual and the fairness with which it attempts to treat all persons. On the surface, it may seem simple, yet those who have delved into it know that this system of federal and state constitutions, statutes, regulations, and common-law decisions is elaborate and complex. It derives from the English common law, but includes principles older than England, along with some principles from other lands. The U.S.
