Dust polarized emission observations of NGC 6334 : BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
(2021-03-11)Context. Molecular filaments and hubs have received special attention recently thanks to new studies showing their key role in star formation. While the (column) density and velocity structures of both filaments and hubs ... -
Dust Spirals and Acoustic Noise in the Nucleus of the Galaxy NGC 2207
(1998)Observations with the Hubble Space Telescope reveal an irregular network of dust spiral arms in the nuclear region of the interacting disk galaxy NGC 2207. The spirals extend from »50 to »300 pc in galactocentric radius, ... -
Dust, Gas, and the Evolutionary Status of the Radio Galaxy 8C 1435+635 at z = 4.25
(1998)We present the results of new rest-frame far-IR observations of the z\4.25 radio galaxy 8C 1435]635, which not only conÐrm that it contains an enormous quantity of dust (as Ðrst inferred from its millimeter-wave detection ... -

The duty cycle of radio galaxies revealed by LOFAR : remnant and restarted radio source populations in the Lockman Hole
(2020-08)Feedback from radio jets associated with Active Galactic Nuclei (AGN) plays a profound role in the evolution of galaxies. Kinetic power of these radio jets appears to show temporal variation, but the mechanism(s) responsible ... -
Duty cycle of the radio galaxy B2 0258+35
(2018-10-11)Context. Radio loud active galactic nuclei (AGN) are episodic in nature, cycling through periods of activity and quiescence. The study of this duty cycle has recently gained new relevance because of the importance of AGN ... -
Duty to care has never been more relevant
(2017-05-12)The recent attack on Westminster Bridge in London sparked an immediate response from the emergency services who tried to save the lives of the many people who had been mowed down by a single perpetrator. The emergency teams ... -

Dwarf-Galaxy Cosmology
(2010)Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our “cosmological backyard”—the Local Group and its vicinity. This special issue of the open-access journal ... -
Dyadic Adaptation in Business-to-Business Markets
(2003-12)Competitive success in business-to-business markets often depends upon the ability of the firm to adapt specifically to the needs of a single customer organization. Research into buyer-seller relationships in industrial ... -
Dyadic art psychotherapy : Key principles, practices and competences
(2014-04)A recent survey indicates that a dyadic parent-child approach to art psychotherapy is being used by 60% of British art psychotherapists working with children and young people with some degree of frequency (Taylor Buck, ... -
Dyadic OPTION : Measuring perceptions of shared decision-making in practice
(2011)Current models of the medical consultation emphasize shared decision-making (SDM), whereby the expertise of both the doctor and the patient are recognised and seen to equally contribute to the consultation. The evidence ... -
Dying at home : access should be equitable
(2010)For a document that is wholly based on statistics, the recent report from the National End of Life Care Intelligence Network (NEoLCIN) on variations in place of death in England (NEoLCIN, 2010) is fascinating reading. It ... -
Dynamic and scalable storage management architecture for Grid Oriented Storage devices
(2008)Most of currently deployed Grid systems employ hierarchical or centralized approaches to simplify system management. However, the approaches cannot satisfy the requirements of complex Grid applications which involve hundreds ... -
Dynamic assessment of learning ability improves outcome prediction following acquired brain injury
(2009)Primary purpose: There is a need to improve the prediction of outcome following acquired brain injury. The previous focus has been on specifying the relative contribution of such variables as pre-morbid intellectual ability, ... -
Dynamic Assignment Protocols for Multi-wavelength Gigabit-PONs
(2011-02-23)The research initiatives addressed in this thesis are geared towards improving the performance of passive optical networks through the development of advanced dynamic bandwidth allocation protocols. In particular, the aim ...
