The formulations and interpretations of some formally analogous expressions of the single-particle scalar quantum wave equations of electrons and photons, propagated in adequate isotropic static media under weak signals and interaction phenomena, are presented in this article. and V prezentovaném článku jsou obsaženy formulace a interpretace některých formálně analogických tvarů jednočásticových skalárních kvantových vlnových rovnic šířících se elektronů a fotonů v přiměřených izotropních statických prostředích při slabých signálech a interakčních jevech.
Thirty-eight specimens of Oochoristica macallisteri sp. n. were recovered from the small intestines of 16 of 123 (13 %) side-blotched lizards, Ota stansburiana Baird et Girard from California, USA. Oochoristica macallisteri sp. n. belongs to a group of species of Oochoristica possessing fewer than 25 testes in a single cluster and circular suckers, namely, O. elongata, O. junkea, O. lygosnmae. O. lygosomalis, O. novaezealandae, O. parvngenitalis and O. sobolevi. The new species can be readily differentiated from the other species of this group by number of lobules of the ovary or number of proglottids and from other species from California by number of testes or shape of vitellarium.
Net photosynthetic rate (PN), transpiration rate (E), stomatal conductance (gs), and leaf water potential (Ψl) of an annual pioneer C4 grass (Agriophyllum squarrosum) were compared under different simulated precipitation events in a field of Hunshandak Sandland, China. The increase of soil water content (SWC) had significant effect on these physiological traits (p<0.001). In the vegetative stage, the values of PN, E, and gs went up sharply when SWC increased at the beginning, while they went down with continuous increase of SWC. PN, E, and gs increased 1.4, 1.7, and 1.7 fold, respectively, with SWC range from 6.7 to 11.6 %. In the reproductive stage, similar trends were found, except for the climate with a higher SWC. This indicated that A. squarrosum was very sensitive to the small increment of SWC which might have a large photosynthetic potential. Ψl increased by about 8 % as the SWC changed from 6.7 to 8.8 %, and then maintained a steady level when the SWC was higher than 8.8 %, while the values of PN, E, and gs kept increasing even after this SWC. This might indicate that the adjustment of Ψl response to the changes of SWC lagged that of the photosynthetic parameters. and M. Z. Liu ... [et al.].
