effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

PRODUCTION OF NEUTRON-RICH Ca ISOTOPES IN TRANSFER-TYPE REACTIONS

Reaction mechanisms involved in the production of neutron-rich isotopes

The reaction mechanisms best suited for the production of neutron-rich nuclei, fragmentation and fission, are discussed. Measurements of the production cross sections of reaction residues together with model calculations allow to conclude about the expected production rates of neutron-rich isotopes in future facilities.

Coulomb dissociation reactions on Mo isotopes for astrophysics applications

Photo-dissociation reactions play an important role in p-process nucleosynthesis, which takes place in supernova explosions. Theoretical calculations of isotopic abundances of the p-nuclei require a vast reaction network linking thousands of isotopes, where most of the reaction rates must be derived from the Hauser-Feshbach statistical model. However, as many rates as possible need to be determ...

Cross-sections for production of neutron deficient Sg - isotopes in reactions

Due to low cross-sections for the production of heaviest nuclei the choice of the optimum reaction for specific nuclides is crucial for nuclear structure investigations based on α-γ-decay spectroscopy, which demand maximum numbers of observed events. Following previous decay studies of No [1] and Rf [2] an experiment to investigate Sg, the next heavier N=153 isotone, for which only rough decay ...
