Mossbauer spectrum measured on ferromagnetic HfFe2 at 296 K, consists of four six-line components and one doublet. The Laves phase HfFe2 has three kinds of crystal structures: cubic MgCu2(C15), hexagonal MgZn2(C14) and ...

This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...

A nonlinear model describing DNA dynamics, called helicoidal Peyrard-Bishop model, is described. It is shown that the model can explain a local opening of a DNA helix during transcription. An impact of friction forces is ...
