Cr-3 Research Paper

Words: 213

Pages: 1

Chromium is a metallic element both odorless and tasteless that occurs naturally in the environment. It occurs in two principal forms: trivalent chromium (chromium-3) and hexavalent chromium (chromium-6) (EPA). Chromium-3 is an important part of the human diet in small amounts. All naturally occurring forms of chromium usually occur in the trivalent state combined with iron or other metal oxides. Cr-3 is the most stable form of chromium and is used industrially for leather tanning, preventing corrosion, and electroplating, and as a component of stainless steel. Chromium-6 occurs when the industrial forms of Cr-3 erode and interact with the natural environment (Barnhart, 1997; Blowes, 2002). It is the second most common groundwater contaminant

Essay about Radio Resource Management and Cognitive Femtocell

overlay cognitive network paradigm. The cognitive femtocell concept leads to simpler and easier proliferation of cognitive radio into practical systems. We highlight the drawbacks and advantages of the proposed network structure with a discussion on research directions for cognitive femtocell architecture. We also provide experimental results to illustrate a general proof of concept for this new modality. INTRODUCTION The need for anytime-anywhere service access over wireless networks has spurred a…
