While the issue on Direct Containment Heating (DCH) was resolved for US reactor plants in the 1990s it was found that the consequences of DCH processes are strongly dependent on the reactor cavity configuration. Therefore, an experimental and analytical program was started in 1998 to investigate melt ejection scenarios for typical German and European reactor designs. Six experiments have been p...

ground settlement is often the most serious concern when tunneling under an old city with numerous historic monuments. a successful engineering design under these conditions would require getting the most out of the ground strength parameters and avoiding any weakening maneuver throughout the operation. knowing that surface settlement is highly affected by tunneling parameters in epb shield tun...

Abstract. In this paper, a Cascaded Lattice Boltzmann Method with second order slip boundary conditions is developed to study gas flows in a microchannel in the slip and transition flow regimes with a wide range of Knudsen numbers. For the first time the effect of wall confinement is considered on the effective mean free path of the gas molecules using a function with nonconstant Bosanquet para...

OBJECTIVES Few studies have examined whether social characteristics of the residential environment are associated with blood pressure after controlling for individual sociodemographic characteristics. Even less is known about the processes by which these associations operate. Therefore, we examined whether distinct dimensions of the residential environment (socioeconomic position and urbanicity...

A simplified dynamic model generates patient-specific estimates of intracranial pressure and suggests a path forward for bringing simulated (SIM) physiologic models to the patient's bedside.

Proterozoic rocks of the southwestern United States exhibit a variety of tectonometamorphic histories that can all be explained by a characteristic looping style of pressure-temperature (P-T) path. The path is fundamentally clockwise. However, because the rocks were cooled isobarically at 3 kbar after tectonism, the cooling path crosses the prograde path, leading to a geometry with a counterclo...

A path analytic study of blood pressure in Swedish families gave evidence for genetic heritability (0.18 for systolic, 0.13 for diastolic) and for cultural heritability, with evidence for an intergenerational difference giving higher estimates of cultural heritability in adults (0.19 for systolic, 0.08 for diastolic). A maternal effect for cultural inheritance was evident for systolic blood pre...

Raman-based geobarometry has recently become increasingly popular because it is an elegant way to obtain information on peak metamorphic conditions or the entire pressure-temperature-time (P-T-t) path of metamorphic rocks, especially those formed under ultrahigh-pressure (UHP) conditions. However, several problems need to be solved to get reliable estimates of metamorphic conditions. In this pa...
