  • Dust and gas mixtures with multiple grain species - a one-fluid approach 

    Laibe, Guillaume; Price, Daniel J. (2014-10-21) - Journal article
    We derive the single-fluid evolution equations describing a mixture made of a gas phase and an arbitrary number of dust phases, generalizing the approach developed by Laibe & Price. A generalization for continuous dust ...
  • The dust budget crisis in high-redshift submillimetre galaxies 

    Rowlands, K.; Gomez, H. L.; Dunne, L.; Aragón-Salamanca, A.; Dye, S.; Maddox, S.; da Cunha, E.; van der Werf, P. (2014-06-01) - Journal article
    We apply a chemical evolution model to investigate the sources and evolution of dust in a sample of 26 high-redshift (z > 1) submillimetre galaxies (SMGs) from the literature, with complete photometry from ultraviolet to ...
  • Dust cloud lightning in extraterrestrial atmospheres 

    Helling, Christiane; Jardine, Moira Mary; Diver, Declan; Witte, Sören (2013-03-01) - Journal article
    Lightning is present in all solar system planets which form clouds in their atmospheres. Cloud formation outside our solar system is possible in objects with much higher temperatures than on Earth or on Jupiter: Brown ...
  • Dust in brown dwarfs and extra-solar planets. IV. Assessing TiO2 and SiO nucleation for cloud formation modelling 

    Lee, G.; Helling, Christiane; Giles, H.; Bromley, S. T. (2015-03) - Journal article
    Clouds form in atmospheres of brown dwarfs and planets. The cloud particle formation processes are similar to the dust formation process studied in circumstellar shells of AGB stars and in Supernovae. Cloud formation ...
  • Dusty disks at the bottom of the initial mass function 

    Scholz, Alexander; Jayawardhana, Ray (2008-01-01) - Journal article
    Isolated planetary-mass objects (IPMOs) have masses close to or below the deuterium-burning mass limit (similar to 15 M-Jup)-at the bottom of the stellar initial mass function. We present an exploratory survey for disks ...
  • Dusty gas with one fluid 

    Laibe, G.; Price, Daniel J. (2014-05-21) - Journal article
    In this paper, we show how the two-fluid equations describing the evolution of a dust and gas mixture can be re-formulated to describe a single fluid moving with the barycentric velocity of the mixture. This leads to ...
  • Dusty gas with one fluid in smoothed particle hydrodynamics 

    Laibe, G.; Price, D.J. (2014-05-21) - Journal article
    In a companion paper we have shown how the equations describing gas and dust as two fluids coupled by a drag term can be re-formulated to describe the system as a single-fluid mixture. Here, we present a numerical ...
  • Dying 'through the law to the law' (Gal. 2.19) 

    Gilthvedt, Gary E. (University of St Andrews, 1990) - Thesis
    In the Letter to the Galatians the law has been superseded by Christ's cross and faith in Christ is contrasted to the law. The juxtaposition of the law and the cross occurs in 2.19, where Paul speaks of them in terms ...
  • Dynamic changes in gene expression in vivo predict prognosis of tamoxifen-treated patients with breast cancer 

    Taylor, Karen J.; Sims, Andrew H.; Liang, Liang; Faratian, Dana; Muir, Morwenna; Walker, Graeme; Kuske, Barbara; Dixon, J. Michael; Cameron, David A.; Harrison, David J.; Langdon, Simon P. (2010-06-22) - Journal article
    Introduction: Tamoxifen is the most widely prescribed anti-estrogen treatment for patients with estrogen receptor (ER)-positive breast cancer. However, there is still a need for biomarkers that reliably predict endocrine ...
  • Dynamic covalent nanoparticle building blocks 

    Kay, Euan Robert (2016-07-25) - Journal article
    Rational and generalizable methods for engineering surface functionality will be crucial to realizing the technological potential of nanomaterials. Nanoparticle-bound dynamic covalent exchange combines the error-correcting ...
  • Dynamic epigenetic changes to VHL occur with sunitinib in metastatic clear cell renal cancer 

    Stewart, Grant D.; Powles, Thomas; Van Neste, Christophe; Meynert, Alison; O'Mahony, Fiach; Laird, Alexander; Deforce, Dieter; Van Nieuwerburgh, Filip; Trooskens, Geert; Van Criekinge, Wim; De Meyer, Tim; Harrison, David James (2016-03-23) - Journal article
    Background: Genetic intratumoral heterogeneity (ITH) hinders biomarker development in metastatic clear cell renal cancer (mccRCC). Epigenetic relative to genetic ITH or the presence of consistent epigenetic changes following ...
  • Dynamic modulation of phosphoprotein expression in ovarian cancer xenograft models 

    Koussounadis, Antonis; Langdon, Simon; Um, In Hwa; Kay, Charlene; Francis, Kyle; Harrison, David James; Smith, V Anne (2016-03-10) - Journal article
    Background: The dynamic changes that occur in protein expression after treatment of a cancer in vivo are poorly described. In this study we measure the effect of chemotherapy over time on the expression of a panel of ...
  • Dynamic molecular control of nanoparticle building block assembly 

    Borsley, Stefan (University of St Andrews, 2016-06) - Thesis
    Nanoparticles have generated much excitement as a result of their often unique properties, inherently dependent on nanoparticle material, shape and size. Virtually all conceivable nanoparticle applications will require ...
  • Dynamic photoinhibition exhibited by red coralline algae in the red sea 

    Burdett, Heidi; Keddie, Victoria; MacArthur, Nicola; McDowall, Laurin; McLeish, Jennifer; Spielvogel, Eva; Hatton, Angela; Kamenos, Nicholas (2014-05-20) - Journal article
    Background: Red coralline algae are critical components of tropical reef systems, and their success and development is, at least in part, dependent on photosynthesis. However, natural variability in the photosynthetic ...
  • Dynamic properties of bright points in an active region 

    Keys, P.H.; Mathioudakis, M.; Jess, D.B.; MacKay, D.H.; Keenan, F.P. (2014-06-20) - Journal article
    Context. Bright points (BPs) are small-scale, magnetic features ubiquitous across the solar surface. Previously, we have observed and noted their properties for quiet Sun regions. Here, we determine the dynamic properties ...
  • Dynamic size tuning of multidimensional optically bound matter 

    Brzobohaty, Oto; Karasek, Vitezslav; Cizmar, Tomas; Zemanek, Pavel (2011-09) - Journal article

  • The dynamical fate of self-gravitating disc fragments after tidal downsizing 

    Forgan, D.; Parker, R.J.; Rice, K. (2015-02-11) - Journal article
    The gravitational instability model of planet/brown dwarf formation proposes that protostellar discs can fragment into objectswith masses above a few Jupiter masses at large semimajor axis. Tidal downsizing may reduce both ...
  • Dynamical history of the Local Group in ΛCDM 

    Banik, Indranil; Zhao, Hongsheng (2016-06-21) - Journal article
    The positions and velocities of galaxies in the Local Group (LG) measure the gravitational field within it. This is mostly due to the Milky Way (MW) and Andromeda (M31). We constrain their masses using distance and radial ...
  • Dynamical torque in CoxFe3–xO4 nanocube thin films characterized by femtosecond magneto-optics : a π-shift control of the magnetization precession
