Biological Test Used in the Assessment of Cytotoxicity and Genotoxicity of Olusosun Landfill: The Lus silicon. Virtually all porous silicon structures created via electrochemical etching or silica reduction are in fact predominantly mesoporous (2–50 nm pore diameter) or macroporous (pore diameter > 50 nm), rather than microporous. Nonetheless, very high surface area (up to 1125 m./g) porous silic

Assessing the Impact of Landfill Leachate on Surface and Ground Water in Bangladesh: A Comparison wdemonstrated the benefits of efficient diversification by formulating a mathematical program for generating the "efficient frontier" to summarize optimal trade-offs between expected return and risk. The Markowitz framework continues to be used as a basis for both practical portfolio construction and
