SkyMapper Filter Set: Design and Fabrication of Large Scale Optical Filters [PDF]

, 2011
The SkyMapper Southern Sky Survey will be conducted from Siding Spring Observatory with u, v, g, r, i and z filters that comprise glued glass combination filters of dimension 309x309x15 mm. In this paper we discuss the rationale for our bandpasses and physical characteristics of the filter set. The u, v, g and z filters are entirely glass filters which

The Efficacy of Surgical Techniques for the Management of Confirmed Vertical Root Fractures: A Systematic Review

Australian Endodontic Journal, Volume 51, Issue 1, Page 218-229, April 2025.
ABSTRACT The aim of the present systematic review was to evaluate the efficacy of surgical techniques for the preservation of a tooth with VRF. We included case series presenting techniques for the treatment of VRFs. Both electronic sources (MEDLINE, EMBASE, Cochrane Central) and reference lists/table of contents of pertinent journals were screened ...

Ionomer structure and component transport in the cathode catalyst layer of PEM fuel cells: A molecular dynamics study [PDF]

J. Chem. Phys. 160, 044910 (2024)
The transport of water and protons in the cathode catalyst layer (CCL) of proton exchange membrane (PEM) fuel cells is critical for cell performance, but the underlying mechanism is still unclear. Herein, the ionomer structure and the distribution/transport characteristics of water and protons in CCLs are investigated via all-atom molecular dynamics ...

Determination of Surface Characteristics, Solubility and Ion Release of a Calcium Silicate Root Canal Sealer

Australian Endodontic Journal, EarlyView.
ABSTRACT This study investigated the solubility of AH Plus Bioceramic sealer (AHPB), the ion release, and the modification of surface characteristics compared to AH Plus (AHP). Solubility was examined according to ISO guidelines in deionised water and phosphate buffer saline (PBS) for 3 months.

Influence of powder/liquid ratio on the radiodensity and diametral tensile strength of glass ionomer cements

Journal of Applied Oral Science, 2010
Clinicians tend to make reductions in glass ionomer power/liquid (P/L) ratios since some materials are difficult to mix and flow into small cavities, grooves or pits.
