Weitzman's approach and conservation of breed diversity: An application to African cattle breeds
Published 2003“…The derived maximum-likelihood trees clearly displayed the geographic distribution and the zebu-taurine admixture of the breeds. We developed a novel scheme to estimate the extinction probability for each breed which considered total population size, change of population size over the last 10 years, distribution of the breed, risk of indiscriminate crossing, organization among farmers, establishment of conservation schemes, political situation of the countries, special traits, sociocultural importance, and reliability of information. …”

Assessment of arsenic contamination in tube-well drinking water in Hanam province
Published 2013“…An environmental health risk assessment was performed to describe the arsenic contamination in tube-well water and assess the health risks of people in Chuyen Ngoai commune, Duy Tien district, Ha Nam province. A total of 150 households were included in the study and results showed that most of the tube-well drinking water samples were contaminated with arsenic (98.7% of the samples before filtration and 80.4% ones after filtration).The concentrations of arsenic in the tube-well water before filtration were high, (mean? …”
