Investigating Mercury Interactions of Rhodotorula Toruloides IR-1395 for Mercury Bioremediation Processes in Aquatic Environments [PDF]
Biological Journal of Microorganism, 2021 Introduction: Nowadays, heavy metals pollution is one of the most important environmental problems. Due to the high cost of common refining methods, the use of microbial biomass is recommended to clean up heavy metals.

The Review of Economic Studies, 2017 We document that in the US over the course of the past century there has been a systematic negative relation between household wealth and business cycle volatility. We develop a microfounded dynamic equilibrium model that contains elements of a traditional Keynesian framework in which economic uctuations can be driven by sunspot-type uctuations in ...

Adsorptive removal of adsorbable organic halogens by activated carbon [PDF]
Royal Society Open Science, 2018 Current research mainly focuses on the reduction of adsorbable organic halogen (AOX) sources, while studies on AOX monitoring and management in the environment are scarce. Organic pollutants in water are mainly fixed by sediments.

Volatility and arbitrage [PDF]
The Annals of Applied Probability, 2018 The capitalization-weighted total relative variation $\sum_{i=1}^d \int_0^\cdot _i (t) \mathrm{d} \langle \log _i \rangle (t)$ in an equity market consisting of a fixed number $d$ of assets with capitalization weights $ _i (\cdot)$ is an observable and nondecreasing function of time.

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry [PDF]
, 2006 Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was

Estimating Stochastic Volatility under the Assumption of Stochastic Volatility of Volatility [PDF]
Risks, 2020 We propose novel nonparametric estimators for stochastic volatility and the volatility of volatility. In doing so, we relax the assumption of a constant volatility of volatility and therefore, we allow the volatility of volatility to vary over time. Our methods are exceedingly simple and far simpler than the existing ones. Using intraday prices for the
