The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq ‎mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq ‎mining district is well known for hosting significan...

objective: osseous defects around dental implants are often seen when implants are placed in areas with inadequate alveolar bone, or around failing implants. bone regeneration in these areas using bone grafts or its substitutes may improve dental implants prognosis. the aim of this study was to prepare and characterize the bioactive glass nanopowder and development of its coating for treatment ...

Ti–6Al–4V scaffolds were fabricated by powder metallurgical space holder technique in this research. The most added magnesium (Mg) powder was evaporated and a skeleton of Ti-6Al-4V alloy was produced. For this purpose Ti-6Al-4V and Mg powders mixture compacted in a steel die by applying uniaxial pressure of 500 MPa before sintering the green product in a sealed quartz tubes at 900 °C for 2 hour...

Apatite-wollastonite (A-W)-phlogopite glass-ceramic is considered to be difficult to resorb, but often, it has been incorporated in particulate form to create new bioactive composites for potential maxillofacial applications. With various compositions, the present work has attempted to prepare apatite-wollastonite (A-W)-phlogopite glass ceramic composites, by applying sintering. Here, three-poi...

phosphorus induces flowering and helps seed formation, but there is a big gap between phosphorus supply from natural sources and agriculture and industry demand. in order to investigate phosphorus feeding over long time from iran regions' apatites on rose plants characteristics, var. black magic in zeoponic culture, an experiment was conducted as factorial on the basis of completely random...

[1] Recent calibration studies have expanded the range of target minerals suitable for cosmogenic He dating to include U and Th‐rich phases such as zircon, apatite, and titanite. These minerals often contain large amounts of radiogenic He that present several analytical challenges for precise and accurate He determinations. In this paper we document the abundance sensitivity and changes in the ...
