The aneuploid plants could sometimes be backcrossed, and in one case a shift in the segregation ratio towards the paternal (non-irradiated) phenotype was observed. We concluded that while the female gametophyte irradiation technique could reduce the number of generations necessary for cytoplasm ...
How the number of required gray levels depends on the gamma of the display In photography, video and computer graphics, the gamma symbol 纬 represents a numerical parameter that describes the nonlinearity of intensity reproduction... SA Klein,T Carney 被引量: 18发表: 0年 Plasma display panel ...
These values are consistent with genetic evidence for the presence of multiple gamma gene loci in human cells. The finding that the number of gamma-globin genes in beta-thalassemia DNA is similar to that in nonthalassemia DNA indicates that a deletion of gamma-globin genes cannot account for ...
Based on their LD50 values appreciable concentrations only selected for further study and their effects on various morphological characters such as plant height, number of branches per plant, number of leaves per plant, days to first flowering, number of capsules per plant, number of seeds per ...
B Ciardi,A Loeb 摘要: If Gamma-Ray-Bursts (GRBs) occur at high redshifts, then their brightafterglow emission can be used to probe the ionization and metal enrichmenthistories of the intervening intergalactic medium during the epoch ofreionization. In contrast to other sources, such as ...
Chromosome analyses were performed on three races (alpha, beta, gamma) of Neotricula aperta which were previously reported to show variation in the chromosome number and pairing in meiosis. We used an air-drying method, which was more reliable for chromosome preparations from fresh animal tissues ...
Also, when similar males were caged with a similar female each day for 5 successive days, the untreated males passed a significantly greater number of spermatophores.关键词: Cydia pomonella DOI: 10.1093/ee/3.4.645 被引量: 17 年份: 1974 ...
In recent years, there has been an increase in the number of reports in the U.S. of the use of drugs, often in conjunction with alcohol, to commit sexual a... ElSohly M.A.,Salamone S.J. - 《Journal of Analytical Toxicology》 被引量: 485发表: 1999年 Gamma-hydroxybutyric acid for...
In a longitudinal study including 16 individuals infected with HIV-1, we studied both the number and function of HIV-specific CD8(+) T cells by comparing HLA-peptide tetramer staining and peptide-induced interferon-gamma (IFN-gamma) production. Numbers of IFN-gamma-producing T cells declined ...
Astrocytes are organized in a ring-shaped network repeating the topology of the interneuron network. It was shown that the number of astrocytes and neurons is approximately the same in the mammalian brain and that the individual astrocytes occupy separate, non-overlapping tissue domains53. The ...
