The effectiveness of manufacturing equipment use taking into account its productivity and reliability for faulty parts of transmission units in municipal buses is estimated. The on-line mode is the most effective method of control allowing the tracking of the processes of technical state changes in municipal buses. As a result of monitoring there were obtained selected data on PAZ-3205 municipal bus operated under winter conditions in the city of Ohrenburg. During the trip there was recorded 39.1 l/100km petrol consumption. The residual life of the PAZ-3205 municipal bus was 1800km.

This study demonstrates the importance of references to religious material in Tacitus’ Annals by analyzing them using cultural memory theory. Throughout his narrative of Julio-Claudian Rome in the Annals, Tacitus includes numerous references to the gods, fate, fortune, astrology, omens, temples, priests, emperor cult, and other religious material. Tacitus, who was not only a historian but also a member of Rome’s quindecimviral priesthood, shows a marked interest in even the most detailed rituals of Roman religious life. Yet his portrayal of religious material also suggests that the system is under threat with the advent of the principate. Traditional rituals are forgotten as the shape of the Roman state changes. Simultaneously, a new form of cultic commemoration develops as deceased emperors are deified and the living emperor and his family members are treated in increasingly worshipful ways by his subjects. The study traces the deployment of religious material throughout Tacitus’ narrative, to show how Tacitus views the development of this cultic ‘amnesia’ over time, from the reign of the cryptic, autocratic, and oddly mystical Tiberius, through Claudius’ failed attempts at reviving tradition, to the final sacrilegious disasters of the impious Nero.

We attempt to treat the very early Universe according to quantum mechanics. Identifying the scale factor of the Universe with the width of the wave packet associated with it, we show that there cannot be an initial singularity and that the Universe expands. Invoking the correspondence principle, we obtain the scale factor of the Universe and demonstrate that the causality problem of the standard model is solved.

Discovering new materials for energy storage requires reliable and efficient protocols for predicting key properties of unknown compounds. In the context of the search for new organic electrolytes for redox flow batteries, we present and validate a robust procedure to calculate the redox potentials of organic molecules at any pH value, using widely available quantum chemistry and cheminformatics methods. Using a consistent experimental data set for validation, we explore and compare a few different methods for calculating reaction free energies, the treatment of solvation, and the effect of pH on redox potentials. We find that the B3LYP hybrid functional with the COSMO solvation method, in conjunction with thermal contributions evaluated from BLYP gas-phase harmonic frequencies, yields a good prediction of pH = 0 redox potentials at a moderate computational cost. To predict how the potentials are affected by pH, we propose an improved version of the Alberty-Legendre transform that allows the construction of a more realistic Pourbaix diagram by taking into account how the protonation state changes with pH.
