THE EXISTING US Renewable Fuel Standard (RFS) makes commercial-scale cellulosic ethanol a priority, calling for 16 billion gallons of cellulosic biofuel production by 2022, sourced from grasses, trees, agricultural residues, and municipal waste. The US Department of Energy “US Billion-Ton Update” study (Downing et al. 2011) suggests that to meet the mandates in the RFS, approximately 66 million...

Investigating the Physicochemical Status of the Sources of Drinking Water Supply in Asadabad City During 2011-2018

Background and Objectives: Sufficient sources of water with acceptable qualities are vital for human survival. Health development and environmental protection have been always depended on providing healthy water supplies. The purpose of this study was to determine the physiochemical status of drinking water sources in Asadabad city during 2011-2018. Materials and Methods: This descriptive stud...

Physics 215 B QFT Winter 2018 Assignment

(a) Consider scattering of an electron (e−) and a positron (e) into e−e+ (so a = b in the notation above). We wish to consider the contribution to the imaginary part of the amplitude for this process which is proportional to QeQ 2 μ where Qe and Qμ are the electric charges of the electron and muon (which are in fact numerically equal but never mind that). Draw the relevant Feynman diagram, and ...

Classical Iwasawa Theory Arizona Winter School 2018

(typeset by Robert JS McDonald, UConn1) Lecture 1. Foundational material. The lecture will briefly cover, without proofs, the background in algebra and number theory needed at the beginning of Iwasawa theory. Throughout, p will denote an arbitrary prime number, and Γ a topological group which is isomorphic to the additive group of p-adic integers Zp. Thus, for each n ≥ 0, Γ will have a closed s...
