Metals In Boat Paint Fragments From Slipways, Repair Facilities And Abandoned Vessels: An Evaluation Using Field Portable Xrf., Andrew Turner, Sean Comber, Aldous B. Rees, Dimitrios Gkiokas, Kevin Solman

School of Geography, Earth and Environmental Sciences

Paint flaking off abandoned vessels or generated during boat repair is hazardous to human health and wildlife. In this study, a means of screening paint fragments using a field portable-X-ray fluorescence (FP-XRF) spectrometer is described. The technique is capable of delivering rapid, surficial measurements of Ba, Cu, Pb and Zn down to concentrations less than 150 μg g(-1), and Sn and Cr to concentrations of a few hundred μg g(-1). Application of the technique to fragments collected from slipways, yards, hardstandings, abandoned boats and ships undergoing maintenance throughout the EU reveal highly variable concentrations of metals among samples from the …

Titanium Phosphate Glass Microcarriers Induce Enhanced Osteogenic Cell Proliferation And Human Mesenchymal Stem Cell Protein Expression, Nilay J. Lakhkar, Day R M, Hae Won Kim, Katarzyna Ludka, Nicola J. Mordan, Vehid Salih, Jonathan C. Knowles

In this study, we have developed 50- to 100-µm-sized titanium phosphate glass microcarriers (denoted as Ti5) that show enhanced proliferation of human mesenchymal stem cells and MG63 osteosarcoma cells, as well as enhanced human mesenchymal stem cell expression of bone differentiation markers, in comparison with commercially available glass microspheres at all time points. We also demonstrate that these microcarriers provide superior human mesenchymal stem cell proliferation with conventional Dulbecco’s Modified Eagle medium than with a specially developed commercial stem cell medium. The microcarrier proliferative capacity is revealed by a 24-fold increase in MG63 cell numbers in spinner flask bioreactor studies …

Dear colleagues,

The International Journal for the Scholarship of Teaching & Learning is undergoing some major changes.

• The layout of the journal has been overhauled, giving it a look that better aligns with the quality of the content. As we continue to struggle with SoTL “counting” as scholarship at some institutions, it is important to package our work in a way that reinforces its value. We hope you enjoy the new look!

• Articles are being assigned DOI (digital object identifier) numbers. All articles, past and present, will be tagged and linked to metadata as indexing is completed over the next …
