Coral calcification in a changing World and the interactive dynamics of pH and DIC upregulation

open access: yesNature Communications, 2017
Coral calcification is dependent on the mutualistic partnership between endosymbiotic zooxanthellae and the coral host. Here, using newly developed geochemical proxies (δ11B and B/Ca), we show that Porites corals from natural reef environments exhibit a ...

Experimental Study on the Fracture Process Zone Characteristics in Concrete Utilizing DIC and AE Methods

open access: yesApplied Sciences, 2019
The present work focuses on investigating the characteristics of the fracture process zone (FPZ) in concrete. The Single-edge notched (SEN) concrete beams under three-points bending are employed for conducting mode I fracture propagation.

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]

open access: yes, 2019
The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.

Measurement of Pressure-Expansion Behaviour Required in Infant Airway Stents Using Digital Image Correlation (DIC) in Rabbit Trachea [PDF]

open access: yes, 2016
INTRODUCTION: Airway stents are used during treatment of tracheal deformities in infants. However, complications including post implantation stent migration occur [1], resulting from too low stent radial stiffness, which causes permanent stent collapse ...
