Reducing Ammonia Losses By Adding FeCI3 During Composting Of Sewage Sludge [PDF]
, 1999 The release of ammonia nitrogen during composting of sewage sludge mixed with a lignocellulosic bulking agent leads to a reduction in the agronomic value of the final compost and to harmful effects on the environment. We propose adding a cheap salt FeCl3

Volatility Options in Rough Volatility Models [PDF]
SSRN Electronic Journal, 2018 We discuss the pricing and hedging of volatility options in some rough volatility models. First, we develop efficient Monte Carlo methods and asymptotic approximations for computing option prices and hedge ratios in models where log-volatility follows a Gaussian Volterra process.

Green Processing and Synthesis, 2018 Jarosite residues in zinc hydrometallurgy are considered as hazardous waste as they contain heavy metals such as Zn and Pb. A novel vacuum reduction and distillation process has been put forward to recover Zn and Pb from jarosite residues.

Nitrogen and sulphur management: challenges for organic sources in temperate agricultural systems [PDF]
, 2005 A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (

Journal of Econometrics, 2011 The study of high-frequency financial data has been one of the most rapidly evolving areas of research over the last decade. We have seen an explosive growth in the availability of such data, which has gone hand in hand with the development of theory for how to analyze the data.

Good Volatility, Bad Volatility and Option Pricing [PDF]
SSRN Electronic Journal, 2016 Advances in variance analysis permit the splitting of the total quadratic variation of a jump-diffusion process into upside and downside components. Recent studies establish that this decomposition enhances volatility predictions and highlight the upside/downside variance spread as a driver of the asymmetry in stock price distributions. To appraise the
