  • I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

  • This paper addresses a vexing problem that has plagued machine reliability professionals.for decades. Despite the best efforts to precisely align rotating machinery shafts,.dynamic movement (mostly manifested by the thermal growth of the machine casings).has resulted in machines operating at less than optimum alignment conditions.

  • At the beginning of the 19th century the description of matter attained, what one would call today, a scientific basis. Dalton1 supported the atomic theory with experiments permitting the development of modern chemistry. The book “A New System of Chemical Philosophy,” describes this new approach. In Fig. 1.1, an excerpt is displayed. Chapters I and II give a summary of the contemporary understanding of nature by analyzing heat and mass, the two basic building-blocks of any material. Chapter I displays the theory of the caloric as it was generally...

  • The evolution of technological advances in infrared sensor technology, image processing, “smart” algorithms, knowledge-based databases, and their overall system integration has resulted in new methods of research and use in medical infrared imaging. The development of infrared cameras with focal plane arrays not requiring cooling added a new dimension to this modality. New detector materials with improved thermal sensitivity are now available and production of high-density focal plane arrays (640×480) has been achieved.

  • Subduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for the release of most of the seismic energy on Earth. There has been considerable achievements done during the past decades regarding the complex interactions between the various processes acting in subduction zones.

  • There have been major breakthroughs in lung surfactant (LS) research over the last two decades that have changed our concept of how and why the material works well at the lung air–water interface. From the initial ideas of a surface active material lining the alveoli to the seminal concepts of how low surface tension is reached, the classical ideas about Comroe’s “extraordinary juice” requires revision and re-thinking.

  • Heteronuclear NMR relaxation measurements and hydro-gen exchange data have been used to characterize protein dynamics in the presence or absence of stabilizing solutes from hyperthermophiles. Rubredoxin from Desulfovibrio gigaswas selected as a model protein and the effect of diglycerol phosphate on its dynamic behaviour was studied. The presence of 100 mMdiglycerol phosphate induces a fourfold increase in the half-life for thermal denaturation ofD.

  • Recent years have witnessed high levels of activity in identifying enzyme systems that catalyse H-transfer by quantum tunneling. Rather than being restricted to a small number of specific enzymes as perceived initially, it has now become an accepted mechanism for H-transfer in a growing number of enzymes. Furthermore, H-tunneling is driven by the thermally induced dynamics of the enzyme. In some of those enzymes that break stable C–H bonds the reaction proceeds purely by quantum tunneling, without the need to partially ascend the barrier.
