V-shaped electro-optic response observed in a chiral ferroelectric smectic liquid crystal
(2008)We report on the observation of V-shaped switching in a ferroelectric liquid crystal cell over a wide range of temperatures. Results of the optical transmittance in the visible region give us the helical pitch for various ... -
Vacancies, interstitials and close Frenkel Pairs on the zinc sublattice of ZnSe
(American Physical Society, 1996)Zinc vacancies (VZn), zinc interstitials (Zni), and ~25 distinct VZn?Zni Frenkel pairs of different lattice separations are observed in ZnSe by the optical detection of magnetic resonance in photoluminescence after 2.5 MeV ... -
Vaccine trials during a pandemic: potential approaches to ethical dilemmas
(2021)Ever since the emergence of the coronavirus disease 2019 (COVID-19), global public health infrastructures and systems, along with community-wide collaboration and service, have risen to an unprecedented challenge. ... -
Vaccinia virus protein A46R targets multiple Toll-like-interleukin-1 receptor adaptors and contributes to virulence
(2005)Viral immune evasion strategies target key aspects of the host antiviral response. Recently, it has been recognized that Toll-like receptors (TLRs) have a role in innate defense against viruses. Here, we define the function ... -
Vaccinia Virus Protein C6 Is a Virulence Factor that Binds TBK-1 Adaptor Proteins and Inhibits Activation of IRF3 and IRF7
(2011)Recognition of viruses by pattern recognition receptors (PRRs) causes interferon-? (IFN-?) induction, a key event in the anti-viral innate immune response, and also a target of viral immune evasion. Here the vaccinia virus ... -
"Vacuum consolidation improves peat ground conditions"
(2010)Trinity College Dublin is currently testing an innovative technique, known as vacuum consolidation, to improve peat ground conditions, as part of the National Roads Authority Fellowship initiative. -
The vagina problem: a step too far in parent-child sex communication with young children
(2024)Parents describe a want for better sex education for their young children compared to their own myth and silence-led experiences while growing up. However, introducing the vagina has proved a challenging step too far for ... -
Valence States in CeVO4 and Ce0.5Bi0.5VO4 Probed by Density Functional Theory Calculations and X-ray Photoemission Spectroscopy
(2014)Ce is one of the few lanthanide elements to exhibit well-defined (III) and (IV) oxidation states in solid state environments and there is therefore ambiguity as to whether CeVO4 should be formulated as Ce(III)V(V)O4 or ... -
Valence-band density of states and surface electron accumulation in epitaxial SnO2 films
(2014)The surface band bending and electronic properties of SnO 2 (101) films grown on r -sapphire by plasma-assisted molecular beam epitaxy have been studied by Fourier-transform infrared spectroscopy (FTIR), x-ray ... -
A validated numerical-experimental design methodology for a movable supersonic ejector compressor for waste-heat recovery
(2013)The aim of this paper is to develop the technical knowledge, especially the optimum geometries, for the design and manufacturing of a supersonic gas-gas ejecto r for a waste heat driven vehicle cooling system. Although ... -
Validated TRNSYS model for forced circulation solar water heating systems with flat plate and heat pipe evacuated tube collectors
(Elsevier, 2011)This paper presents a validated TRNSYS model for forced circulation solar water heating systems used in temperate climates. The systems consist of two flat plate collectors (FPC) and a heat pipe evacuated tube collector ... -
