Mechanisms of osteocyte stimulation in osteoporosis
(Elsevier, 2016-05-10)
Experimental studies have shown that primary osteoporosis' caused by oestrogen deficiency results in localised alterations in bone tissue properties and mineral composition. Additionally, changes to the lacunar-canalicular ...
The tensile ductility of cellular solids: the role of imperfections
(Elsevier, 2016-10-11)
Metallic and polymeric foams typically possess a low tensile failure strain of a few percent despite the fact that the parent solid can have high ductility (10% or more). This is remarkable as foams are bending-dominated ...
Selective laser sintering of hydroxyapatite/poly-epsilon-caprolactone scaffolds
(2010)
Selective laser sintering (SLS) enables the fabrication of complex geometries with the intricate and controllable internal architecture required in the field of tissue engineering. In this study hydroxyapatite and ...
Osteocyte differentiation is regulated by extracellular matrix stiffness and intercellular separation
(Elsevier, 2013-07-18)
Osteocytes are terminally differentiated bone cells, derived from
osteoblasts, which are vital for regulation of bone formation and resorption. ECM stiffness and cell seeding
density have been shown to regulate osteoblast ...
Linear irregular wave generation in a numerical wave tank
(Elsevier, 2015-07-09)
In the design of any floating or fixed marine structure, it is vital to test models in order to understand the fluid/structure interaction involved. A relatively inexpensive method, compared to physical model testing, of ...
Proof-of-concept and evaluation of a dual function visible/NIR camera for iris authentication in smartphones
(Institute of Electrical and Electronics Engineers, 2015-05)
As a robust method of person authentication, iris biometrics is making its way in to consumer devices such as smartphones. Current iris image acquisition devices typically work under controlled environment and constrained ...
Environmental impacts of milk powder and butter manufactured in the Republic of Ireland
(Elsevier, 2016-11-11)
The abolition of the milk quota system that was in place in Europe was abolished in 2015, which instigated an immediate increase in milk production in many European countries. This increase "will aid in addressing the ...
Using Wikis to facilitate team work: German and Irish students' perspectives
(All Ireland Society for Higher Education (AISHE), 2011)
Enhanced collaboration among multicultural European countries is necessary for effective
enterprise development and innovation. The current climate of an increasingly competitive
global economy provides opportunities to ...
Micromechanical finite element modelling of thermo-mechanical fatigue for P91 steels,
(Elsevier, 2016-01-21)
In this paper, the cyclic plasticity and fatigue crack initiation behaviour of a tempered martensitic ferritic steel under thermo-mechanical fatigue conditions is examined by means of micromechanical finite element modelling. ...
Impact of biochar addition to soil on greenhouse gas emissions following pig manure application
(2013)
The application of biochar produced from wood and crop residues, such as sawdust, straw, sugar bagasse and rice hulls, to highly weathered soils under tropical conditions has been shown to influence soil greenhouse gas ...
