An 8 to 10 year review of the rotaglide total knee replacement
(2009)Mobile-bearing knee arthroplasty (MBKA) is an alternative to fixed-bearing knee arthroplasty. This was a retrospective study of the Rotaglide Total Knee System. We present the results of the monitoring of 77 patients (85 ... -
8-13 micron dust emission features in Galactic bulge planetary nebulae
(2001)A sample of 25 IR-bright planetary nebulae (PNe) towards the Galactic bulge is analysed through 8–13μm spectroscopy. The classification of the warm-dust emission features provides a measure of the C/O chemical balance, and ... -
An 8.56 keV absorption line in the hyperluminous X-ray source in NGC 4045: Ultra-fast outflow or cyclotron line?
(2022-04-21)We report on the discovery of an absorption line at $E=8.56^{+0.05}_{-0.11}$ keV detected with a significance of $>3.3\sigma$ in the NuSTAR and XMM-Newton spectra of a newly discovered hyperluminous X-ray source (HLX, ... -
An 8.56 keV Absorption Line in the Hyperluminous X-Ray Source in NGC 4045: Ultrafast Outflow or Cyclotron Line?
(2022-04-21)We report on the discovery of an absorption line at E=8.56−0.11+0.05 keV detected with a significance of >3.3σ in the NuSTAR and XMM-Newton spectra of a newly discovered hyperluminous X-ray source (L X > 1041 erg s−1) in ... -
An 80-kpc Ly alpha halo around a high-redshift type-2 quasi-stellar object
(2009)We announce the discovery of an extended emission line region associated with a high redshift type-2 QSO. The halo, which was discovered in our new wide-field narrow-band survey, resides at z = 2.85 in the Spitzer First ... -
The (85)Rb(p,n)(85)Sr reaction and the modified proton optical potential
(American Institute of Physics (AIP), 2009)The cross sections of the astrophysically relevant (85)Rb(p,n)(85)Sr(g,m) reaction have been measured between E(c.m). = 2.16 and 3.96 MeV. The cross sections have been derived by measuring the gamma radiation following the ... -
85- GHz BIMA observations of the double-hotspots radio galaxy 3C 20
(2001-01)We present 85-GHz observations of the archetypal double-hotspot radio source 3C20 made with the BIMA millimetre array. The resolution of BIMA allows us to separate the two components of the eastern hotspot. By comparing ... -
An 850-μ SCUBA map of the Groth Strip and reliable source extraction
(2005-03-01)We present an 850-μm map and list of candidate sources in a subarea of the Groth Strip observed using the Submillimetre Common-User Bolometer Array (SCUBA). The map consists of a long strip of adjoining jiggle-maps covering ... -
A 90-GHz Asymmetrical Single-Pole Double-Throw Switch with >19.5-dBm 1-dB Compression Point in Transmission Mode Using 55-nm Bulk CMOS Technology
(2021-08-25)The millimeter-wave (mm-wave) single-pole double-throw (SPDT) switch designed in bulk CMOS technology has limited power-handling capability in terms of 1-dB compression point (P1dB) inherently. This is mainly due to the ... -
A Retórica da Academia e os Limites da Comunicação
(Conselho de Pesquisas em Educação e Ciências, 2009)In areas of design practice, the paradigm of knowledge has not been clearly articulated, but some of its characteristics appear to include a valorisation of subjectivity; plurality of interpretation; objects that embody ... -
A-Wardpβ : Effective hierarchical clustering using the Minkowski metric and a fast k-means initialisation
(2016-11-20)In this paper we make two novel contributions to hierarchical clustering. First, we introduce an anomalous pattern initialisation method for hierarchical clustering algorithms, called A-Ward, capable of substantially ... -
AALLA: Attack-Aware Logical Link Assignment Cost-Minimization Model for Protecting Software-Defined Networks against DDoS Attacks
(2023-11-02)Software-Defined Networking (SDN), which is used in Industrial Internet of Things, uses a controller as its “network brain” located at the control plane. This uniquely distinguishes it from the traditional networking ... -
The AAO/UKST SuperCOSMOS Ha survey
(2005)The UK Schmidt Telescope (UKST) of the Anglo-Australian Observatory completed a narrow-band H plus [NII] 6548, 6584°A survey of the Southern Galactic Plane and Magellanic Clouds in late 2003. The survey, which was the last ... -
Abbey Steel : Conquering the steel recycling market
(Oxford University Press (OUP), 2010)This chapter summarizes a case study involving recycled steel trader Abbey Steel Ltd. The company, with the assistance of the University of Hertfordshire Academics enhanced its customer retention by designing and implementing ... -

Abell 1367: a high fraction of late-type galaxies displaying HI morphological and kinematic perturbations
(2018-04-21)To investigate the effects the cluster environment has on late-type galaxies (LTGs), we studied HI perturbation signatures for all Abell 1367 LTGs with HI detections. We used new Very Large Array HI observations combined ... -
Aberrant driving behaviours amongst New Zealand truck drivers
(2002-01-01)Research using the driver behaviour questionnaire (DBQ) has found that aberrant driving behaviours can be categorised into: errors, lapses and violations (and aggressive violations, depending on the version of the DBQ ... -
