Dam-Foundation Rock Interaction Effects in Earthquake Response of Arch Dams

The dynamic response of Morrow Point Dam to Taft ground motion is presented for a wide range of properties of the dam, foundation rock, impounded water, and reservoir boundary materials. Based on these response results, the effects of dam-foundation rock interaction (considering damping, inertia, and flexibility of the foundation rock) with empty reservoir are investigated. The significance of dam-foundation rock interaction effects ignored in standard analyses that consider flexibility of the foundation rock but not its inertia or damping—material and radiation—effects is then identified. Finally, the combined effects of dam-foundation rock interaction, dam-water interaction, and reservoir boundary absorption are studied.

The Deterministic Prediction of Damage in Light Water Nuclear Reactors

Abstract Localized corrosion phenomena, including pitting corrosion, stress corrosion cracking, and corrosion fatigue, are the principal causes of corrosion-induced damage in electric power generating facilities and typically result in more than 50% of the unscheduled outages. Prediction of damage, so that repairs and inspections can be made during scheduled outages, could have an enormous impact on the economics of electric power generation. To date, prediction of corrosion damage has been made on the basis of empirical/statistical methods that have proven to be insufficiently robust and accurate enough to form the basis for the desired inspection/repair protocol. In this paper, we describe a deterministic method for predicting localized corrosion damage. We have used the method to illustrate how pitting damage functions might be predicted for low pressure steam turbines downstream of the Wilson line, where a thin condensed liquid layer exists on the stainless steel blade surfaces. Our calculations show that the pitting corrosion damage function is very sensitive to the oxygen content of the steam, with increasing oxygen levels resulting in more extensive and deeper pitting for a given time of observation.

Impact of Inflammatory Bowel Disease and High-Dose Steroid Exposure on Pupillary Responses to Negative Information in Pediatric Depression

IBD may be associated with increased sensitivity to negative emotional stimuli above and beyond depression diagnosis. Depressed youths potentially demonstrate affective blunting, emotional avoidance, or a failure to regulate emotion after exposure to negative emotional information. Thus, there seem to be unique contributions of medical disease and depression to physiological indications of emotional reactivity, but these factors do not seem to interact.

<i>Chicago fade</i>: putting the researcher’s body back into play

The second piece of the series depicts a highly meaningful incident of physical interaction outside the ring while the ethnographer was conducting fieldwork in a boxing gym, tracking the fabrication of the pugilistic habitus through apprenticeship (Wacquant, 2004). In a painful haircutting session, the author receives not only a black‐American style fade , but confirmation of his full membership in the group. This text emphasizes the fundamental importance of accounting for ethnographer’s lived experience as intersubjective and embodied; it is through our lived bodies in action that we relate to the world that is shared with the informants (Merleau‐Ponty, 1962; Bourdieu and Wacquant, 1992; Crossley, 1996). Here ethnography emerges as a corporeal activity that plumbs the processes through which knowledge of a particular culture becomes acquired and deployed, the researcher being an active, socially constituted agent producing effects in the field (Wacquant, 2009).

Reservoir Bottom Absorption Effects in Earthquake Response of Concrete Gravity Dams

Utilizing a recently developed analytical procedure, linear responses of the tallest non‐overflow monolith of Pine Flat Dam to Taft ground motion are presented for a range of properties for the reservoir bottom materials and various assumptions for the impounded water and foundation rock. In these analyses, the alluvium and sediments at the reservoir bottom, up‐stream of the dam, are modeled by a reservoir bottom that partially absorbs incident hydrodynamic pressure waves. Based on these response results, it is demonstrated that the earthquake response of dams is increased by dam‐water interaction and decreased by reservoir bottom absorption with the magnitude of these effects depending on the flexibility of the foundation rock and on the component of ground motion. It is also shown that the significance of the response of dams to vertical ground motion was overestimated in earlier studies assuming a rigid reservoir bottom.
