Electron mobility on a surface of dielectric media: influence of surface level atoms

We calculate the contribution to the electron scattering rate from the surface level atoms (SLA), proposed in [A.M. Dyugaev, P.D. Grigoriev, JETP Lett. 78, 466 (2003)]. The inclusion of these states into account was sufficient to explain the long-standing puzzles in the temperature dependence of the surface tension of both He isotopes and to reach a very good agreement between theory and experiment. We calculate the contribution from these SLA to the surface electron scattering rate and explain some features in the temperature dependence of the surface electron mobility. This contribution is essential at low temperature $T<0.5$ when the He vapor concentration is exponentially small. For an accurate calculation of the electron mobility one also needs to consider the influence of the clamping electric field on the surface electron wave function and the temperature dependence of the He3 chemical potential.Comment: 6 pages, 1 figur

The problem of forming time transspektive professional development of future specialists in modern conditions

The article deals with the concept of "individual time transspective" in the context of the professionalization of the individual. The author proves the necessity to study student?s professional transspective. There were allocated individual time distortions of transspective of professional development: decenteration in the past and the future, contraction of perspective, discrete transspective and its splitting in the allocation of alternative options for professional developmentВ статье раскрывается понятие «индивидуальная временная трансспектива» в контексте профессионализации личности. Обосновывается необходимость изучения профессиональной трансспективы у учащихся профессиональной школы. Выделены искажения индивидуальной временной трансспективы профессионального становления: децентрации в прошлое и в будущее, укорочение перспективы, дискретность трансспективы и ее расщепление в процессе выделения альтернативных вариантов профессионального развити
