Probability samples

The primary objective of this study is to elucidate the chemical speciation of copper (Cu) and conduct an assessment of the magnitude and probability of contamination of Cu in soil samples procured from the Pb/Zn mining, at the Hich village, Dong Hy district, Thai Nguyen province, in order to furnish critical data pertinent to the environmental stewardship of soil resources within this geographical domain.

The analysis is carried out by the hypothesis testing and the event tree method. The probability of detection for diversion of 8 kg Pu is found to be less than 95% if a large size granule consisting of small size particles gets sampled for measurements. To increase the probability of detection more than 95%, first, a new Material Balance Area (MBA) structure consisting of more number of Key Measurement Points (KMPs) is designed.

This paper examines episodes of banking sector distress for a large sample of countries, highlighting the experience of Japan. We estimate a model that links the onset of banking problems to a set of macroeconomic variables and institutional characteristics. The model predicts a high probability of banking sector distress in Japan in the early 1990s, matching actual developments closely, and suggests that the Japanese episode fits a well-established pattern characterizing banking sector problems elsewhere.
