Laumontite and heulandite are extensively developed as metamorphic minerals in sandstones of the Late Cretaceous Nanaimo Group, Vancouver Island and Gulf Islands, British Columbia. Major postdepositional changes in the sandstones also include widespread carbonate cementation and replacement, alteration of plagioclase and biotite, and development of a phyllosilicate matrix. The sequence apparently is depth-zoned, with heulandite present only in the upper 1000 m of section, and laumontite developed in the upper 2500 m. The zeolite assemblages probably were developed during burial metamorphism, as subject to controls of permeability and suppression by a high chemical potential of CO,. Comparable assemblages should be expected in similar clastic sequences found in other portions of the Cordillera, particularly the thick Mesozoic successions of the Intermontane and Insular Fold Belts.Les mineraux laumontite et heulandite, d'origine metamorphique, sont presents en grande quantite dans des gres du Groupe Nanaimo du CrCtace Superieur, dans 1'Ile Vancouver et les iles du Golfe en Colombie-Britannique. De plus, les transformations majeures, post-d6positionnelles des gres sont caract6risCes par la cimentation et le remplacement en carbonates, I'alteration des plagioclases et de la biotite et le dkveloppement d'une matrice phyllosilicatee. La sequence est apparemment profondement zonee: la heulandite est presente seulement dans le premiers 1000 m de la section, la laumontite s'est developpee dans les 2500 m supkrieurs. Les assemblages de zeolites se sont probablement developpes pendant I'enfouissement metamorphique et sont dus au controle de la permeabilite et de la suppression par un potentiel chimique eleve de C o n . On s'attend ce que des assemblages de ce type soient trouves dans des sequences clastiques semblables situkes dans d'autres parties des Cordilleres, particulitrement les successions MCsozoiques des ceintures plissees de "1'Intermontane" et de "1'Insular".[Traduit par le journal]

EVE Online is well-knowns for allowing bad behavior like scamming, stealing and betraying, and previous research has explored how that behavior is enabled and governed by the affordances of the game. Comparatively little attention has been paid to the “community norms” that are often contrasted with the developer’s management. Here, I consider the influence of culture in China on the play of EVE. Where the narrative of globalization suggests that the world is becoming more homogenous, anthropologists look at the micro-level to see how new forms of modernity are created. EVE’s (intended) single-server design, liberal economy, and radical freedom are particularly characteristic of an assemblage of global flows, and the game’s neoliberal fantasy is transformed in play.In EVE, tradition is used by Chinese people to make sense of their modern situation, explaining to themselves why Chinese players play more conservatively than others. Without suggesting that Chinese players are universally or essentially different from players in the rest of the world, these differences can be at least partly attributed to the culture of modern China. I consider the lifeworld of a typical EVE player in China, who are over 95% young men, focused on the need to save money and provide for their family, both their parents and their potential children. Players frequently compared the conservative attitude toward money in the actual world with their own conservative play of EVE, or their perceived conservative play of other players.

Experiments on melt quenching by the injection of water from below were conducted. The test section represented one-dimensional flow-channel simulation of the bottom injection of water into a core melt in the reactor cavity. The melt simulant was lead-bismuth alloy. For the experimental conditions employed (i.e., melt depth and water flow rates), it was found that: 1) the volumetric heat removal rate increased with increasing water mass flow rate and 2) the non-condensable gas mixed with the injected water had no impairing effect on the overall heat removal rate. Implications of these findings for ALWR ex-vessel coolability are discussed.
