The scattering of a hyperthermal Xe from a graphite(0001) surface has been studied using a molecular beam-surface scattering technique and molecular dynamics (MD) simulations. The angular and velocity distributions of scattered Xe atoms were measured at incidence energies from 0.45 to 3.5 eV, three incidence angles of 15◦, 35◦ and 60◦ and the surface temperatures of 300 K and 550 K. The observe...
The authors previously reported equations, derived from the Nutrient Biomarker Study within the Women's Health Initiative, that produce calibrated estimates of energy, protein, and percentage of energy from protein consumption from corresponding food frequency questionnaire estimates and data on other factors, such as body mass index, age, and ethnicity. Here, these equations were applied to yi...
Energy poverty is a temporary condition, yet non-negligible share of the Australian population suffers persistent energy disadvantage. Using Household, Income and Labour Dynamics in Australia (HILDA) survey, we observe that single individuals, single-parent households those with disabled household member are at high risk poverty. This also true for non-working individuals immigrants from non-En...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
