Petroleum hydrocarbon contamination poses a serious threat to soil ecosystems and may limit the effectiveness of earthworm-assisted bioremediation. This study investigated the survival of two earthworm species, Eudrilus eugeniae (epigeic) and Alma millsoni (endogeic), in soil contaminated with varying concentrations of a mixture of petroleum products (MPP). It also evaluated the effect of poultry manure amendment on their...

This study examines the asymmetric effects of Foreign Direct Investment (FDI) on domestic investment, focusing on crowd-in and crowd-out effects. Using the Non-linear Autoregressive Distributed Lag (NARDL) model, it analyzes positive and negative FDI changes as a percentage of Gross Domestic Product (GDP). Findings reveal a rapid adjustment mechanism (-0.8981, p-value 0.000) to restore long-run equilibrium. Positive FDI...
