The last 5500 years of climate change and environmental response in the northern Benguela Coastal Upwelling are reconstructed by means of three sediment cores from the inner shelf off central Namibia.The study is based on nutrient (δ15N, δ13C) and productivity proxies (accumulation rates of total organic carbon; ARTOC).Reconstructed sea
Abstract Acid fracturing fluids can effectively improve the microporous structure of coal, thereby enhancing the permeability of coal seam and the efficiency of gas drainage.To explore the effects of acid fracturing fluids on the pore structure modification of coal samples from different coal ranks, Calculator hydrochloric acid-based acid fracturin
In this article, we investigate the applicability of quantum machine learning for classification tasks using two quantum classifiers from the Qiskit Python environment: the variational quantum circuit and the quantum kernel estimator (QKE).We provide a first evaluation on the performance of these classifiers when using a hyperparameter search on si
Enviromental preservation plays an important role in the sustainability of living ecosystems.Environmental damage is caused by irresponsible human behavior Bias Tools so that environmental damage enters a very concerning stage.Therefore, environmental literacy needs to be developed from an early age in elementary school students as candidates for f
Abstract Nodavirus, or nervous necrosis virus (NNV), is the causative agent of viral encephalopathy and retinopathy (VER), a severe disease affecting numerous fish species worldwide.European sea bass, a cultured species of great economic importance, is highly susceptible to the disease.To better understand the response of this organism to NNV, we c
