Consistency analysis of sand cone and nuclear method results in compacted soils

In this study, the ratio of compaction was determined by sand cone and nuclear test methods performed in the same place. The normal distribution fitness of the compaction percentiles was tested by the Anderson-Darling test and normal distribution was normalized by subjecting the unsuitable Water Content values to Jonson transformation. Findings the results obtained with the nuclear method reveal that both methods are consistent with each other in terms of mean data, with lower and more variables in the Sand Cone method. It is recommended to test the consistency of the results obtained by the nuclear method. Also, because of the rapid results, statistical model has been investigated for adapting the results of nuclear method to the sand cone method. For this purpose, regression analysis and artificial neural network models were investigated; artificial neural networks were seen to provide successful predictions inside of the found models.

The role of e- capture in neutrino-nucleosynthesis

In the first stage of this paper, we perform detailed calculations of the electron capture cross sections on nuclei under laboratory conditions. We use the nuclear method known as proton-neutron quasi-particle random phase approximation (pn-QRPA). In the second stage, we translate the above mentioned e--capture cross sections to the stellar environment. As a concrete nuclear target we use the 56Fe and the 66Zn isotopes, which belong to the iron group nuclei and play prominent role in stellar nucleosynthesis: i) in pre-supernova phase and ii) in supernova phase.
