First results are reported of a new abundance study of neutron-capture elements in the ultra-metal-poor (&sqbl0;Fe&solm0;H&sqbr0;=-3.1) halo field giant star CS 22892-052. Using new high-resolution, high signal-to-noise ratio spectra, abundances of more than 30 neutron-capture elements (Z>30) have been determined. Six elements in the 40<Z<56 domain (Nb, Ru, Rh, Pd, Ag, and Cd) have been detecte...
in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...
The striking similarity between the solar distribution of r-element abundances in the 56 ≤ Z ≤ 76 range and the corresponding abundance pattern observed in the ultra-metalpoor star CS 22892-052 is analysed. It is found that such an observation does not necessarily imply that the whole A >∼ 70 distribution of r-nuclides, including Th, suspected to have been engulfed in CS 22892-052 at the same t...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
There are some records of early attempts to maintain BF Trypanosoma brucei in vitro [1, 2], but short-term propagation, in the presence of feeder cells (L-cells), was not achieved until 1967 [3]. Continuous propagation was not reported until 1977, when the Lister 427 strain (clone 052 from GAMC) was successfully propagated in RPMI 1640 medium with 25 mM HEPES and 20% heatinactivated FBS, in the...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
