1. Steam condensation in a water pool and its effect on thermal stratification and mixing
Abstract : The Pressure Suppression Pool (PSP) of a Boiling Water Reactor (BWR) is a large heat sink designed to limit the containment pressure by condensing steam released from the primary coolant system. The development of thermal stratification is a safety concern since it leads to higher containment pressures than in completely mixed conditions, and can affect the performance of systems such as the emergency core cooling and containment spray, which the use PSP as a source of water.

2. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water
Abstract : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. READ MORE

3. Investigations of passive safety systems in LWRs : melt coolability with bottom coolant injection, light gas effects on a passive containment cooling system
Abstract : The key objectives in introducing passive features in thesafety systems for Light Water Reactor (LWR) are to increasetheir reliability, to simplify the design of the plants and toimprove performance and economics. Component and integralsystem tests in scaled facilities are required for optimizingthe design and for certification of these safety systems. READ MORE

4. Molecular mechanisms involved in prokaryotic cycling of labile dissolved organic matter in the sea
Abstract : Roughly half of the global primary production originates from microscopic phytoplankton in marine ecosystems, converting carbon dioxide into organic matter. This organic matter pool consists of a myriad of compounds that fuel heterotrophic bacterioplankton. READ MORE

5. Articular and epiphyseal cartilage : its formation, maintenance and repair
Abstract : Long bones develop via a series of ordered processes, initiated from mesenchymal stem cell condensation, cartilage anlagen formation, followed by central cell hypertrophy and vascular invasion and the finalized by the formation of primary and secondary ossification centers (SOC), where the latter is also called endochondral ossification. As long bone develops, it can be distinguished in to several morphologically distinct parts: the main shaft of a long bone, called diaphysis; a narrow disc of growth plate, providing a continuous supply of chondrocytes for longitudinal growth; a thin layer of articular cartilage at the ends of epiphysis, supporting joint movement, and a SOC, sandwiched between the two pieces of cartilage.
