Squeezing and entanglement in quasiparticle excitations of trapped Bose-Einstein condensates
(2002)We estimate the amount of temperature-dependent squeezing and entanglement in the collective excitations of trapped Bose-Einstein condensates. We also demonstrate an alternative method of temperature measurement for ... -
Squeezing and temperature measurement in Bose-Einstein condensates
(2001)In this paper we review recent developments in the theory of quasi-particle coupling in trapped Bose–Einstein condensates. We discuss prospects for observing squeezed quasi-particles in finite-temperature condensates. -
Squeezy Green Balls: Promoting Environmental Awareness through Playful Interactions
(ACM Press, 2016-10-16)We need collective action to tackle global warming. However, research shows that people switch off from being concerned about the environment because they are often too busy, or fail to appreciate their ability to make a ... -
SR-12813 lowers plasma cholesterol in beagle dogs by decreasing cholesterol biosynthesis
(1997-09-01)SR-12813 inhibits cholesterol biosynthesis in Hep G2 cells via an enhanced degradation of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. Here we also show that SR-12813 inhibits cholesterol biosynthesis in vivo. ... -
Stabbing injuries
(1997-12-01)Stabbing injuries are likened to an iceberg as the seemingly small laceration or puncture wound provides a marker below which major organ of vessel trauma may exist. Low velocity pentrating injuries commonly occur in the ... -
Stabilisation of amorphous drugs under high humidity using pharmaceutical thin films
(2013-08)In this study, the stabilization effects of three polymers on four model drugs (felodipine, fenofibrate, carbamazepine, and celecoxib) under saturated humidity were investigated. Three different types of thin films (solid ... -
Stabilisation of deoxyribonuclease in hydrofluoroalkanes using miscible vinyl polymers
(2006-09-28)A mix of biocompatible macromolecules (poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP)) has been shown previously to enhance the physical stability of non-aqueous pharmaceutical suspensions. The aim of this ... -
Stability analysis of the MAAT feeder airship during ascent and descent with wind disturbances
(2013-12-19)This paper looks into with the aerodynamic properties and stability of the feeder airship in the framework of MAAT project. FP7 MAAT project is based on the concept of two different types of airships (the cruiser and the ... -
Stability and expression of bacterial genes in replicating geminivirus vectors in plants
(1989-04-11)Bacterial beta-glucuronidase (gus) and neomycin phosphotransferase (neo) genes were introduced into coat protein replacement vectors based on DNA A of tomato golden mosaic virus (TGMV). Recombinant gus and neo vectors up ... -
Stability characteristics of cylindrical fibres in an electrodynamic balance designed for single particle investigation
(2002)An electrodynamic balance (EDB) of the double ring double disc type has been designed for studying single microparticles. It allows electrostatic particle injection and recovery as well as alignment of elongated particles. ... -
Stability of cloud orbits in the broad-line region of active galactic nuclei
(2011-02-11)We investigate the global dynamic stability of spherical clouds in the broad-line region (BLR) of active galactic nuclei (AGN), exposed to radial radiation pressure, gravity of the central black hole (BH) and centrifugal ... -
Stability of penicillin G, ampicillin, amikacin and oxytetracycline and their interactions with food in in vitro simulated equine gastrointestinal contents
(1995-05)Penicillin G was extensively (84.7 per cent) and amikacin moderately (14.4 per cent) degraded when incubated for one hour in a chloride buffer at pH 1.9 designed to mimic the equine gastric pH. Ampicillin and oxytetracycline ... -
Stability of radiative relativistic shocks to global oscillations
(2008-09)Thermally emitting, radiative, Newtonian shocks exhibit a global oscillatory instability. The luminosity variations that accompany such oscillations raise the possibility that, if relativistic shocks that emit nonthermal ... -
Stability of set-shifting and planning abilities in patients with schizophrenia
(2004)Patients with schizophrenia have deficits in executive function that involve attentional set-shifting and planning ability. It is unclear, however, whether such deficits are stable during the course of the illness or if ... -
The stability of stratified layers within ventilated enclosures
(University of Hertfordshire, 2006)The project consists of experimental and numerical investigation of buoyancy-dominated flow leading to thermal stratification in ventilated spaces for the range of Re from 4,000 to 50,000 and Rio below 40. In the evolution ... -
Stadium : Video Installation
(Musée d'art contemporain de Montréal, 2008)The significance of Stadium lies in its critical interrogation of the legacy, use and infiltration of historical socialist imagery in contemporary imaging. The work is filmed in the Olympiastadion in Berlin, the infamous ... -

Staff-student Partnership in Practice in Higher Education : The Impact on Learning and Teaching
(Elsevier, 2013-10-10)This staff-student collaborative project involved six small project teams each composed of staff and undergraduate students studying within the University of Hertfordshire, UK. Each project team engaged in a mini-project ...
