Renewable energies such as solar or wind energy are highly unreliable, owing to uncertain energy intensity and discontinuity. This shortcoming could be overcome by converting renewable energies to a form such as chemical fuel storage. In the present study, we created an energy conversion system that uses microwave heating and a carbon receptor to transform CO2, a greenhouse gas, into CO chemical fuel. The parametric investigation found that increasing the gasification temperature and feed gas temperature decreased [...] 1626 11832 |

Demographic Differences in the Quantity, Mass, and Anatomical Location of Ingested Plastic in Northern Fulmars (Fulmarus glacialis): A Review and Reconsideration of NE Pacific Ocean Samplesby
Abstract
On the Washington and Oregon coast of the NE Pacific Ocean from 2008-2015, we found that juveniles represented 83% of Northern Fulmars that were beached. In comparison to older birds, juveniles averaged more mass and pieces of plastic in stomachs. This reflected relatively larger plastic loads in the cranial stomach section, the proventriculus, which we found was associated with relatively large accumulations in the caudal stomach section, the ventriculus. We estimate that the proventriculus could retain almost 10 [...] 1104 25427 |

Potential Impact of UWWT Effluent Discharges on Ruditapes decussatus: An Approach Using BiomarkersAbstract
The use of biomarkers in bivalves has gained significance as a reliable method for the assessment of the presence and effect of contaminants in aquatic ecosystems. However, it is important to note that the biomarkers respond not only to contaminant loadings and bioavailability but also to environmental stress. Therefore, the association between biomarkers and contamination/pollution should be conducted cautiously as the environmental factors also affect their response. These factors should be integrated into the as [...] 1338 9803 |
Modelling the Cumulative Number of COVID-19 CasesAbstract
Each country has its own characteristics of COVID-19 infection trajectory and epidemic waves. Differences in government-implemented restrictions and social regulations result in variability of the virus transmissions and spread dynamics. This in turn results in various shapes of the growth function used to represent and describe the propagation of infection. Statistical methods are applied to fit non-linear functions to represent daily time-series data of the cumulative numbers of COVID-19 cases. The aim of this wo [...] 2001 12016 |

Challenges in the PFAS Remediation of Soil and Landfill Leachate: A ReviewAbstract
The use of per-and poly-fluoroalkyl substances (PFAS) has resulted in the contamination of different environmental matrices. In EU countries, the sites contaminated with PFAS are usually remediated by excavating the soil and disposing of it in a landfill, as no in-situ or on-site techniques capable of treating large quantities of soil cost-effectively have been developed. Landfilling of PFAS-contaminated soil is one of the sources of PFAS in landfill leachate. In this paper, the physical and chemical treatment meth [...] 3984 34775 |

Electrochemical Oxidation of Perfluorooctanesulfonate by Magnéli Phase Ti4O7 Electrode in the Presence of TrichloroethyleneAbstract
This study examined the degradation of perfluorooctanesulfonate (PFOS) in electrochemical oxidation (EO) processes in the presence of trichloroethylene (TCE). The EO experiment was performed in a gas-tight reactor using Magnéli phase titanium suboxide (Ti4O7) as the anode. The experimental data demonstrated that 75% of PFOS (2 μM) was degraded at 10 mA/cm2 current density in 30 min without TCE present in the solution, while the presence of 76 μM TCE apparently inhibited the degradation of PFOS, reducing its r [...] 2526 16277 |
How to Prioritize Voluntary Dietary Modificationby
Abstract
Environmentally motivated voluntary diet modifications are the focus of much research and public discourse. Yet the nuanced multi-faceted, multi-dimensional nature of agriculture-earth interactions, and limited public environmental knowledge likely combine to undermine the efficacy of environmentally motivated dietary shifts, squandering limited good will. To counter this, here I devise two related indices for crudely estimating importance of various environmental impacts of alternative dietary choices. Based on th [...] 1448 9720 |
