This study investigated the composition and character of organic matter on suspended particulate material (SPM) in the Columbia River estuary system to determine the contribution of biological activity in lateral bays to the greater nutrient cycle of the river. Water samples were collected during neap and spring tidal forcing (25...
In high voltage direct current(HVDC) systems
transmission technology, a.c. power is
converted(rectified) to d.c. power by means of a
controlled rectifier bridge. This d.c. power is then
transmitted through a d.c. link to another
converter(inverter) where it is converted back to a.c.
power by means of another controlled rectifier bridge....

Introduction: People whose faces look untrustworthy tend to receive harsher social evaluations, including more severe criminal sentences. Yet little is known about how much facial trustworthiness reflects individuals’ behavioral histories. We examined whether adolescent histories of delinquency and substance use predict strangers’ perceptions of young men’s facial trustworthiness. Methods: Boys...
This study investigates the applicability of the database-assisted design (DAD) methodology to predict structural reactions in a light-framed wood structure subjected to fluctuating wind pressures. Structural influence functions were determined on a 1/3-scale light-frame wood structure, which was then subjected to a wind flow, while the surface pressures and structural...
The assessment of losses during extreme events such as hurricanes is important for performance-based design of residential buildings. In this paper, a methodology for estimating the probability of debris impact, specifically roof sheathing panels, to windows as a result of hurricanes is introduced and applied to a series of illustrative...
