Advances in air quality research – current and emerging challenges
(2022-04-11)This review provides a community’s perspective on air quality research focusing mainly on developmentsover the past decade. The article provides perspectives on current and future challenges as well asresearch needs for ... -
Addressing patients’ communication support needs through speech-language pathologist-nurse information-sharing: Employing ethnography to understand the acute stroke context
(2022-02-22)Purpose: To explore how speech-language pathologists and nurses share information about the communication support needs of stroke patients through structured information-sharing routes and to consider how the two disciplines ... -
Effects of incidental reminders on prospective memory in children
(2022-03-21)Prospective memory (PM) involves remembering to carry out intended actions in the future (e.g., posting a letter on the way to school or passing on a message) and is important for children’s independent functioning in daily ... -
Accretion mode versus radio morphology in the LOFAR Deep Fields
(2022-02-16)Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical behaviours, which in arcsec- to ... -
"Relic jet activity in “Hanny’s Voorwerp” revealed by the LOFAR Two metre Sky Survey"
(2022-06-10)We report new observations of "Hanny's Voorwerp" (hereafter HV) taken from the second data release of the LOFAR Two-metre Sky Survey (LoTSS). HV is a highly-ionised region in the environs of the galaxy IC2497, first ... -
Childhood trauma and schizotypy in non-clinical samples: A systematic review and meta-analysis
(2022-06-29)The association of early life adversities and psychosis symptoms is well documented in clinical populations; however, whether this relationship also extends into subclinical psychosis remains unclear. In particular, are ... -
An Integrated Risk Assessment and Collision Avoidance Methodology for an Autonomous Catamaran with Fuzzy Weighting Functions
(IEEE, 2022-04-22)Collision avoidance and risk assessment are open problems to be practically addressed in maritime transportation. In high-speed vessels this problem becomes more challenging due to manoeuvring and reaction time constraints. ... -
Fatigue life and self-induced volumetric changes of CARDIFRC
(2010-09-01)A class of ultra-high-performance fibre-reinforced cementitious composites (UHPFRCC) has been developed at Cardiff university and registered under the trade name CARDIFRC. The method of its production and its mechanical ... -
Behavior of RC beams retrofitted with CARDIFRC after thermal cycling
(2010-01)This study investigates the effect of thermal cycling on the performance of concrete beams retrofitted with CARDIFRC, a new class of high performance fiber-reinforced cement-based material that is compatible with concrete. ... -
Durability performance of self-compacting concrete
(2012-12)Although self compacting concrete (SCC) is currently used in many countries, there is a fundamental lack of the intrinsic durability of the material itself. This article presents the outcomes from a research program on ... -
Durability of similar self-compacting concrete batches produced in two different EU laboratories
(2013)The present study intends to evaluate the sensitivity of self-compacting concrete (SCC) mixtures, cast in two different laboratories of the European Union, with a focus on rheological parameters, mechanical characteristics ... -
Development of a new Ultra High Performance Fibre Reinforced Cementitious Composite (UHPFRCC) for impact and blast protection of structures
(2015-07-30)Ultra High Performance Fibre Reinforced Cementitious Composites (UHPFRCCs) represent a class of cement composites which have superior characteristics in terms of material properties. Their mechanical and fracture behaviour ... -
Dauerhaftigkeitsindikatoren für SVB entwicklung einer leistungsorientierten bemessung der dauerhaftigkeit von SVB
(2010)The fundamental principle behind the development of SCC has been the nanoscale tailoring of cementitious matrices. Although self-compacting concrete (SCC) is currently used in many countries, there is a fundamental lack ... -
By-product materials in the production of next generation SCC
(CRC Press/Balkema, 2008)Self-Compacting Concrete (SCC) is an advanced type of concrete that can flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. In hardened ... -
Towards more sustainable and environmentally-friendly concretes : The use of silica fume
(WITPress, 2009)Concrete is the most widely used construction material. At the same time, however, the concrete industry is a major CO2 emitter thus contributing towards global warming. While enhanced efficiency in the production of ... -
Self-consolidating concrete and its bond to reinforcement
(Precast Prestressed Concrete Institute, 2010)Research has shown that high slump concrete mixtures can exhibit bond problems especially at the top-cast bars due to blocking of bleed water underneath the reinforcement. As far as self-consolidating concrete is concerned ... -
Development of uhpfrcc with the use of materials a vailable in Cyprus
(Czech Concrete Society, 2011)The aim of the specific study is to present the results of an extended work on the development of an UHPFRCC with the use of materials available in Cyprus. The fundamental idea for the development of this high performance ... -
Green concrete - Recycling construction waste
(Czech Concrete Society, 2011)Within the European Union, the construction and demolition wastes come to at least 180 million tons per year. Roughly 75% of the waste is disposed to landfill, despite its major recycling potential. The bulk constituents ... -
Reproducibility of self-compacting concrete batches between two different EU laboratories
(2012)Self Compacting Concrete (SCC) offers a wide variety of advantages during casting. Considering the worldwide uniformity of guidelines concerning the composition and casting instructions for the production of fresh SCC, ...
