In the treatment of superficial lesions with 8-13 MeV electrons, lead shields are often used to protect the underlying tissue. Measurements were made with film and ion chamber to analyse various aspects of external and internal shielding in electron beam therapy. Data were obtained on the thickness of lead required for shielding, the effect of blocking on dose-rate, electron-backscattering from...

abstract consensus in the international community has grown over the past two years that hiv/aids poses a threat to development, security, and economic growth. a few studies over the last ten years have looked at the impact on workers and their employers. with momentum building to prevent new infections and treat those already afflicted, more information is needed to assess economic impacts and...

Price discovery function analyses the dynamics of futures and spot price behavior in an asset’s intertemporal dimensions. The present study examines bullion, metal, energy commodity prices through Granger causality Johansen–Juselius cointegration tests. test results show bidirectional between returns for gold, silver, aluminum, lead, nickel, zinc. Johansen shows that are long-run equilibrium pa...
