Uranium (U) concentration and the activities of 238U, 234U, and 230Th were determined for groundwaters, spring waters, and lake water collected from the Shihongtan sandstone-hosted U ore district and in the surrounding area, NW China. The results show that the groundwaters from the oxidizing aquifer with high dissolved oxygen concentration (O2) and oxidation-reduction potential (Eh) are enriche...

In complex acoustic choruses, competitive call timing interactions are often important in female mate choice. In the treefrog Dendropsophus ebraccatus, neighboring males’ advertisement calls tend to overlap and females prefer lagging calls. Males that produce leading advertisement calls are thus at a disadvantage relative to lagging males. In this study, I propose a novel strategy by which lead...

Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could result in a biased estimation of formation properties but could provide a means to estimate in situ stress from sonic logging data. In order to properly account for the formation property alteration, we propose an iterative numerical approach to c...

Seven mite species belonging to the genus Syringophilopsis Kethley, 1970 (Acari: Prostigmata: Cheyletoidea) are recorded from 10 passeriform host species from the USA. Three new species are described and illustrated: Syringophilopsis polioptilus sp. n. from Polioptila caerulea (Linnaeus) (Polioptilidae); S. empidonax sp. n. from Empidonax hamrnmondii (Vesey) and Empidonax wrightii Baird (Tyrann...

The chromosomes of 15 species of Iridaceae of the genera Alophia, Cipura, Eleutherine, Neomarica and Trimezia (subfamily Iridoideae) were examined after conventional Giemsa staining. The karyotypes of Alophia drummondii (2n = 14+1B, 28, 42 and 56), Cipura paludosa (2n = 14), C. xanthomelas (2n = 28) and Eleutherine bulbosa (2n = 12) were asymmetric; Neomarica candida, N. caerulea, N. humilis, N...

Earlier phylogenetic analyses of the marine Rhodobacteraceae (class Alphaproteobacteria) genera Leisingera and Phaeobacter indicated that neither genus might be monophyletic. We here used phylogenetic reconstruction from genome-scale data, MALDI-TOF mass-spectrometry analysis and a re-assessment of the phenotypic data from the literature to settle this matter, aiming at a reclassification of th...

The results of studying quality indicators (organoleptic, physicochemical, microbiological) puree from the fruits Lonicera caerulea L. (blue honeysuckle) before and after pressure treatment are presented. It was found that organoleptic microbiological meet requirements established by standard for these products. content organic acids in during processing increases due to an increase level lacti...
