In this article, the effects of using municipal solid waste compost in corn cultivation on animal’s health were assessed. The study was run at the Soil and Water Research Institute of Iran and followed an incomplete strip block design composed of six treatments and three repeats. The treatments were control, with no fertilizer or municipal solid waste compost, multiple combinations of N, P, and K chemical fertilizers, and municipal solid waste compost which were used either once or twice a year. Mature corn plants (Single Cross 704) from the lowest collar were sampled during the end of summer 2019. Corn samples were examined for cadmium, lead, nickel, and zinc concentration. Using the Oracle Crystalball software, health risks were estimated for sheep, dairy cows, beef, broiler, and laying poultry. The highest exposure to cadmium, nickel, and zinc was observed in sheep feeding corn cultivated in T5 treatment, but the highest exposure to lead was observed in sheep fed with corn cultivated in T2 treatment. Cd, Pb, Ni, and Zn exposure and related risk indices were lower than the reported reference values. It can be concluded that the quality of fodder corn grown in the treatments in this study was within the safe range in terms of heavy metal content and did not threaten the health of the investigated animals.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show significant correlations between the spectral index and both cross-helicity and magnetic energy density. Notably, at lower speeds or closer distances, the correlation coefficient (CC) between the cross-helicity and spectral index is smaller than that between the magnetic energy density and spectral index. Conversely, at higher speeds or greater distances, the correlation with cross-helicity becomes comparable to or even exceeds that with magnetic energy density. Additionally, as the speed increases or the heliocentric distance decreases, cross-helicity, magnetic energy density, proton temperature, and the absolute values of the spectral index show a mostly upward trend. Moreover, cross-helicity, absolute values of the spectral index, and CC between the magnetic energy density and spectral index exhibit a similar trend with the speed, initially rising and then declining at the highest speed bin.

The influence of the manufacturing acidity (pH 6, 8, 10, and 12) on the thin-film formation possibility, properties of copper oxide, and its performance as a glucose sensor were studied. Comprehensive standard analyses, including x-ray diffraction, ultraviolet–visible, scanning emission microscopy, and energy-dispersive x-ray were used to characterize the synthesized CuO thin films. Cyclic voltammetry measurements were conducted to evaluate the oxidation and reduction potentials of the CuO-based non-enzymatic glucose sensor. The sensing ability was tested by Amperometry measurement. The electrocatalytic performance of copper oxide for glucose detection was excellent and highly stable at pH 10. Structural analysis showed that the best nanostructures in terms of purity, film roughness, and substrate adhesion were formed at pH 10, which positively affected its sensor performance. The electrocatalytic performance of this film was good and stable. It also had the highest glucose sensitivity of 21.488 mA mM<sup>−1</sup> cm<sup>−2</sup> with a detection limit of 1.1 mM as indicated by Amperometric measurement.

The X-ray diffraction patterns reveal that the prepared sample crystallizes in cubic symmetry. Our paper provides an insight into the electrical transport behavior of our compound. Indeed, different conduction models are applied to interpret the electrical conductivity response. It was observed that the transport properties are influenced by hopping mechanisms across different temperature ranges, which explains both the changes in DC conductivity and the movement of charge carriers with temperature variations. This confirms that the charge carriers undergo thermal activation. The variation of the exponent s as a function of temperature indicates the presence of Quantum Mechanical Tunneling (QMT), Correlated Barrier Hopping (CBH), Non-overlapping Small Polaron Tunneling (NSPT), and Overlapping Large Polaron Tunneling (OLPT) in the transport properties. At the temperature range [160–540 K], the AC conductivity is found to obey “double Jonscher power law.” Besides, the frequency dependence of the conductivity obeys “single Jonscher power law” at higher temperatures. Additionally, the conductivity spectrum shows a high-frequency plateau, which suggests percolation behavior.</p></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 4","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
