Listed here are the orbital energies, total energies, and ionization energies for ground-state configurations of uranium ions U I to U XCII. These values have been computed with the relativistic Dirac-Fock code due to Desclaux. The ground-state electronic configuration for each ion is determined by comparing the total energies of neighboring configurations and selecting the one with the minimum value. The ionization energies are obtained by building differences between the total energies of the respective ions with and without the valence electron. The term values of the uranium ions have been assigned through comparison with the term values of ionized atoms with the same configuration and the same number of electrons as given in the tables of Moore. The tables presented here should find application in the calculation of opacities in uranium plasmas. 相似文献

Bioactive compounds are components extracted from biological matrices that may offer physiological health benefits and have nutritive value. The present study characterized bioactive lipid components such as fatty acids, phytosterols, policosanol, and triterpenes from table olives. The table olives were processed according to the green Spanish-style method. The obtained results indicate that phytosterol fraction constitutes the major portion of the total unsaponifiable matter. The analysis of phytosterols showed the presence of 11 compounds, β-sitosterol the predominant one. The policosanol composition indicated that hexacosanol, tetracosanol, octacosanol, and docosanol were the main compounds, accounting for over 85% of total policosanols. Pentacyclic triterpenes (cycloartenol and 24-methylene cycloartenol) were found at a higher level (over 85%) compared to tetracyclic triterpenes (β-amyrin, δ-amyrin). These findings reveal that processed table olives contain an interesting amount of various bioactive compounds compared to marine and other floral biological matrices. Thus, processed table olives represent an interesting natural functional food that presents high stability and bioavailability of their natural bioactive ingredients. Practical Applications: Nowadays, with health food gaining popularity among consumers, the demand for natural bioactive compounds and functional food is expanding considerably all over the world. This study focuses on analyzing bioactive lipid components from processed table olives. Fruits were processed according to the green Spanish-style method. The salt content of the brine was adjusted to the minimum sodium chloride value required by the Codex Alimentarius Comission, which is 5%, taking into consideration people suffering from hypertension. This concentration is considered the minimum amount of salt necessary to exhibit antibacterial activities. Considering the results obtained, processed table olives present one of the most valuable potential resources for bioactive lipid compounds and have a considerable ability to preserve the stability of their lipid components. Thus, the food industry in Mediterranean countries can promote processed table olives as conventional functional food with no need for any enrichment or fortification. 相似文献
