I’ll close by acknowledging that there are costs to my approach. If Italy is not given a bailout, the country may have a “disorderly default,” meaning the government simply stops honoring its commitments to pay bondholders. That is bad for individual bondholders, but it also could hurt ...

Natural uranium consists of the long-lived radioactive isotopes, mainly,234U,235U and238U, with molar abundances of 0.0057, 0.72, and 99.27%, respectively. In natural uranium, the activity ratio of238U to235U is reported as 21.546,47. In the present study, the activity ratio of238U/235U was...
Therefore, this test indicates that the two-directional model is better than one-directional model analysis. In conclusion, two-directional system GMM is the best model for explaining the behavior of deposit insurance policy with respect to the ratio of retail deposits to total assets and the ...
In a vial, prepare the hole transport layer solution of 3,6-bis(4-vinylphenyl)-9-ethylcarbazole (VPEC)30 dissolved in chlorobenzene solvent in the ratio of 3 mg:1,000 µL. Sonicate the solution for 30 min in the ultrasonic bath and filter the sonicated solution in a vial with a 15...
The term hazard ratio is often used interchangeably with the term relative risk ratio to describe results in clinical trials. This is not strictly correct as there are subtle and important differences. It is useful to understand the meaning of the term and also be able to identify when it is...
