Even though the effect of oil price shocks on macroeconomics has been extensively investigated, the literature on how efficiency in household energy use affect crude oil price volatility is yet explored. This study unveils whether household energy efficiency lower crude oil price volatility asymmetrically in the United States using the historical and forecast dataset that spans from 1970:Q1-2040:Q1. Applying the multivariate case of Quantile-on-Quantile Regression, the empirical results show that household energy efficiency dampens crude oil price volatility with a stronger connection in quantiles before the median quantiles of crude oil price volatility.

This study investigated the cytotoxicity effects of daily sub-lethal oral doses of VO on the bone marrow of male Oryctolagus cuniculus after 21 days. Male O.
View Article and Find Full Text PDFAtrazine (ATRA) and ciprofloxacin (CPRO) are widely detected, persistent and co-existing aquatic pollutants. This study investigated effects of 14-day single and joint ATRA and CPRO exposure on juvenile Clarias gariepinus. Standard bioassay methods were used to determine responses of oxidative stress, hepatic condition, and immunological biomarkers on days 7 and 14.

- Propranolol (PRO) is a beta-blocker used for various health issues, and this study examined its effects on juvenile Clarias gariepinus (African catfish) when exposed to sublethal concentrations of the drug.
- The experiment established a median lethal concentration (LC) of 9.48 mg/L and tested lower concentrations over 21 days, measuring fish growth and various blood and biochemical parameters.
- Results showed significant changes in blood cell counts and some liver enzyme activity due to PRO exposure, but most health indicators returned to normal after a 7-day recovery in clean water, suggesting that monitoring PRO levels in water environments is important.
Article Synopsis
- * The findings suggest that natural resource extraction initially supports economic growth, but after a certain point (natural rents to GDP ratio of 12.18%), it leads to increased carbon emissions, highlighting a U-shaped relationship referred to as the "carbon curse."
- * A total of 17 countries are identified as being at risk of the carbon curse, indicating a need for policies that promote renewable energy and energy efficiency to foster sustainable development in these regions.
