Inconsistencies in modelling interstitials in FeCr with empirical potentials

We present empirical potential and Density Functional Theory results of interstitials in FeCr and pure Cr. Results show that potentials for the original and revised two-band model, a recently introduced third two-band model, and for the revised concentration-dependent model produce errors of up to multiple eV in formation and binding energies for Fe-containing interstitials in pure Cr. Fe-interstitial binding in Cr is much stronger than Cr-interstitial binding in Fe according to Density Functional Theory, but all four potentials still strongly overestimate the binding strength. At the Fe-rich end errors in empirical potentials are smaller and most of the errors are not a linear extrapolation in concentration of the larger errors in pure Cr. Interstitial formation energies in Fe-rich FeCr are underestimated by all four empirical potentials, but much less so than in pure Cr. In Fe-rich FeCr the revised concentration-dependent model produces Cr-interstitial binding energies quite similar to Density Functional Theory values, while all three two-band models show almost no binding or repulsion.Accepted Author Version(OLD) MSE-

FACTORIAL ANALYSIS OF THE REASONS OF TYPE 2 DIABETES MELLITUS FROM THE SELECTED URBAN AND RURAL SUBJECTS OF BANGLADESH

Background Type 2 Diabetes Mellitus has been a major concern for the people of Bangladesh where various factors are risky in this regard. That’s why the study was designed in a way to assess the risk factors. Materials and methods Sixty subjects played a part in the study of 30-90 years old, were branded into four varied groups. A number of factors including age, height, weight status, smoking habits, calorie intake, physical activity and past medical history were analyzed. Both BMI and FBG level were correlated. Results BMI status advocates that obese subjects of Group-1 (80%) and Group-4 (66.67%) higher than 50% whereas group-2 (26.67%) and group-3 (46.67%) contains obese subjects below 50%. According to FBG level, Group-1 (average 16.876 mmol/L) and Group-4 (average 14.12 mmol/L) were in high risk than Group-2 (average 7.265 mmol/L) and Group-3 (10.03 mmol/L) subjects. 45% subjects had a family history of diabetes and about 50% male smokers were obese. 95% of subjects didn’t have any physical exercise. The rate of new patients with no family history is increasing (48.33%). Conclusion This study states individual correlation between BMI & FBG. Food calorie intake condition, data related to obesity and family history were also calculated
