Triboluminescence and X-Rays

Triboluminescence is shown to produce X-rays from the nanoparticles (NPs) that form as the sticky acrylic adhesive of Scotch tape is peeled from the polyethylene (PE) roll in a vacuum. Prior to peeling, atoms in the adhesive are not under electromagnetic (EM) confinement and have full thermal kT energy. But upon peeling, the atoms in NPs that form in the gap between adhesive and PE are under EM...

We present results from the analysis of deep ROSAT HRI and PSPC observations of the spiral galaxy M81. The inferred total (0.5–2 keV band) luminosity of M81 is ∼ 3×10 ergs s, excluding the contribution from identified interlopers found within the D25 ellipse. The nucleus of the galaxy alone accounts for about 65% of this luminosity. The rest is due to 26 other X-ray sources (contributing ∼ 10%)...

General Practice and X-Rays

Genetics and the British insurance industry.

Genetics and genetic testing raise key issues for insurance and employment. Governmental and public concern galvanised the British insurance industry into developing a code of practice. The history of the development of the code, issues of genetic discrimination, access to medical information, consent and the dangers of withholding information and the impact on the equity of pooled risk are exp...

Preparation and characterization of Epoxy/Lead oxide nano-composite for shield against gamma and X-rays

Polymer nano-composites are a group of materials that represent proper mechanical, chemical, thermal and optical properties due to the presence of certain percentages of a filler in a polymeric matrix. In this study lead oxide nanoparticles were prepared by direct precipitation method. Then the lead oxide-epoxy resin nanocomposite was prepared by mixing (without solvent) with different weight p...
