Cytogeography of Pilosella officinarum (Compositae): altitudinal and longitudinal differences in ploidy level distribution in the Czech Republic and Slovakia and the general pattern in Europe.
BACKGROUND AND AIMS Pilosella officinarum (syn. Hieracium pilosella) is a highly structured species with respect to the ploidy level, with obvious cytogeographic trends. Previous non-collated data indicated a possible differentiation in the frequency of particular ploidy levels in the Czech Republic and Slovakia. Therefore, detailed sampling and ploidy level analyses were assessed to reveal a b...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولSocial egg freezing: a reproductive chance or smoke and mirrors?
Autologous human oocyte cryopreservation allows storing woman’s eggs to be used later by the same donor when therapeutic or elective reasons induce women to postpone motherhood. In the case of non-medical motivation, this practice is termed social freezing. By shifting the awareness from a medical procedure to social relations, frozen oocytes are becoming polemic bio-objects, which pose new que...
متن کاملSperm morphology and reproductive success
fertilization potential, decisions on how to improve sperm morphology remain difficult to address. Smoking, alcohol consumption, caffeine intake and drug use can affect fertility; however, a conclusive connection between these factors and sperm morphology has not been demonstrated. Furthermore, use of dietary supplements and vitamins has not been shown to directly affect sperm morphology. While...
متن کاملTransverse modes of a laser resonator with Gaussian mirrors.
Analytical methods are presented for transverse mode analysis of a laser resonator having spherical mirrors with a Gaussian reflectivity profile. The modes of this type of resonator have a form similar to that of the conventional Gaussian modes, but it is necessary to define an additional beam parameter to meet the selfconsistency requirement for resonator modes. Stability of both the conventio...
