WebDec 5, 2024 · The aim of the paper is to present a study of the magnetocaloric effect and the nature of phase transition in the Gd80Ge15Si5 (S1), Gd75Ge15Si5Ni5 (S2), Gd75Ge15Si5Pr5 (S3) and Gd75Ge15Si5Nd5 (S4) alloys. The magnetic entropy changes determined for studied samples, under external magnetic field ~3T, were 11.91, 12.11, 5.08 and 4.71 … WebThis guidance covers the general methods to be used in determining the first-order degradation model input. Frequently, biotransformation laboratory studies do not follow a first-order degradation pattern; yet standard pesticide fate models (e.g. PRZM, EXAMS) require first-order degradation inputs.
