Doing confirmation with ja/nee hoor. Sequential and prosodic characteristics of a Dutch discourse particle

This paper offers sequential-interactional and prosodic observations on the confirmation forms ja hoor / nee hoor ('yes'+particle hoor / 'no' + hoor) in Dutch talk-in-interaction, as part of a larger analysis of the form and function of the particle hoor. We show that ja/nee hoor is used as a marked confirmation in sequentially specifiable context-types. When used as a response to queries, the speaker marks doing confirmation as programmatically motivated. When used in environments that further §[ sequence expansion], ja/nee hoor resists such expansion. Thus, the use of ja/nee hoor is motivated by an orientation to multiple levels of discourse organization. Ja/nee hoor is associated with recurrent pitch contours which are systematically distributed across environments of use. We discuss our findings in relation to previous findings on the use of hoor in Dutch

Sexual Orientation, Disclosure and Earnings

Gay/bisexual workers tend to earn less than other men. Does this occur because of discrimination or because of selection? In this paper we address this question and collect new information on workplace disclosure to separate out discrimination effects from selection effects. Using a large sample of recently graduated men in the Netherlands, we find that gay/bisexual workers earn about 3 to 4 percent less than other men. Our disclosure estimates, however, provide little evidence that the labor market discriminates against gay/bisexual workers. They rather support the selection story, most prominently observed among undisclosed gay/bisexual workers who concentrate in lower paid occupations, and earn about 5 to 9 percent less than other men.sexual orientation, disclosure, earnings, discrimination, selection

Conformational Dynamics of the Plug Domain of the SecYEG Protein-conducting Channel

The central pore of the SecYEG preprotein-conducting channel is closed at the periplasmic face of the membrane by a plug domain. To study its conformational dynamics, the plug was labeled site-specifically with an environment-sensitive fluorophore. In the presence of a stable preprotein translocation intermediate, the SecY plug showed an enhanced solvent exposure consistent with a displacement from the hydrophobic central pore region. In contrast, binding and insertion of a ribosome-bound nascent membrane protein did not alter the plug conformation. These data indicate different plug dynamics depending on the ligand bound state of the SecYEG channel.

Shock-operated valve would automatically protect fluid systems

Glandless valve shuts down high-pressure fluid systems when severe shock from an explosion or earthquake occurs. The valve uses a pendulum to support the valve closure plug in the open position. When jarred, the valve body is moved relative to the pendulum and the plug support is displaced, allowing the plug to seat and be held by spring pressure

Aeroacoustics of a porous plug jet noise suppressor

The aeroacoustics of a porous plug jet noise suppressor was investigated. The predicted flow features of isentropic plug nozzles for different pressure ratios or exit flow Mach numbers, throat areas, ratios of the plug to annular nozzle radii, mass flow rates and the available run times possible with the existing compressed air supply system, are compiled. The dimensions and the coordinates of the contour of typical isentropic external expansion plugs with different exit flow Mach numbers are listed. Design details of the experimental facility and the plug nozzle selected for experimental aeroacoustic studies are reported. The analytical flow prediction by method of characteristics of a conical porous plug nozzles is initiated. The role of the shape, size, and porosity of the plug surface in achieving over a perforated conical plug a nearly isentropic shockfree supersonic flow field which is closely similar to the flow field of a contoured isentropic plug nozzle is examined

Electrical self-aligning connector

A self-aligning electrical connector device includes a receptacle component having a conically contoured interior and a plug component having a correspondingly contoured conical body receivable in the receptacle component. The plug component has a number of spaced conductive ring elements with a mating face and the receptacle component includes corresponding spaced conductive ring elements providing mating interface with the mating face of the ring elements of the plug component when connected to it. Each ring element of the receptacle component has several segmented portions which defect downwardly when the plug component is inserted. A biasing force is asserted against the face of the ring elements of the plug component providing positive electrical contact and connection between the ring elements of the components

Sprue cutoff tool for molded FCC plugs

Sprue removal operation is accomplished by positioning plug on tool bed, adjusting blades, and moving handle down for cutting process. Blades are raised to remove trimmed plug

Thermocouple installation

A thermocouple assembly which includes a plug having a pair of small diameter holes near one end thereof which are spaced a small distance apart to leave a thin quantity of plug material between the holes is presented. There are a pair of thermocouple wires extending through the different holes and with the outer ends of the wires joined to the thin quantity of plug material which lies between the holes to form a thermocouple junction

A plug-and-play ripple mitigation approach for DC-links in hybrid systems

© 2016 IEEE.In this paper, a plug-and-play ripple mitigation technique is proposed. It requires only the sensing of the DC-link voltage and can operate fully independently to remove the low-frequency voltage ripple. The proposed technique is nonintrusive to the existing hardware and enables hot-swap operation without disrupting the normal functionality of the existing power system. It is user-friendly, modular and suitable for plug-and-play operation. The experimental results demonstrate the effectiveness of the ripple-mitigation capability of the proposed device. The DC-link voltage ripple in a 110 W miniature hybrid system comprising an AC/DC converter and two resistive loads is shown to be significantly reduced from 61 V to only 3.3 V. Moreover, it is shown that with the proposed device, the system reliability has been improved by alleviating the components' thermal stresses
