The article analyzes the use of new digital technologies in transport education considering the Moscow Automobile and Road Construction State Technical University (MADI) as an example. The results Massive Open Online Courses (MOOC) and other electronic systems in the training of engineers using on specialty «Land transport and Technological Vehicles» are given. Positive opportunities of online courses using arise in the organization of student extracurricular activities and the implementation of a differentiated approach in training. Different content of online courses in the areas of training makes it difficult to use MOOC in the practice of general engineering education. The authors suggest using the Modular Object-Oriented Dynamic Learning Environment (Moodle) which is a free web application that provides to create websites for online learning. The experience of using the online resource «Information system MADI» («IS-MADI: Physics») to study Physics, created by MADI’s teachers, is also considered. This experience makes to conclude that using of the Internet resource «IS-MADI: Physics» awakes interest of students to learn Physics. In a whole students begin to understand that knowledge of Natural Science disciplines gives them powerful tool to create and to exploit modern cars and roads, they begin understand importance of Physics.
The influence of plastic deformation on temperature dependence of carrier concentration n and mobility p in PbS crystals has been studied. Comparison of the results obtained with selective etching patterns from original and deformed crystals makes it possible t o conclude that during the plastic deformation there takes place a dissolution of precipitates by passing of dislocations through them. As a results, rows of point defects appear along t h e path of dislocation movement which may be the cause of a change in n and p due t o deformation. A change in the electron scattering mechanism below 110 K has been discovered.Der EinfluB der plastischen Deformation auf die Temperaturabhllngigkeit der Triigerkonzentration n und die Beweglichkeit p in PbS-Kristallen wurde untersucht. Ein Vergleic h der Ergebnisse mit den Btzfiguren aus selektiver Btzung des Originals und der deformierten Kristalle ermoglicht die SchluBfolgerung, daB wghrend der plastischen Verformung dadurch eine Auflosung von Ausscheidungen auftritt, daB die Versetzungen durch diese hindurchwandern. I m Ergebnis erscheinen Punktdefektreihen entlang der Bewegung der Versetzungen, dieverursacht durch die Verformungeine Bnderung von n und p hervorgerufen haben konnten. Eine Anderung in dem Mechanismus der Elektronenstreuung unterhalb 110 K wurde gefunden.
