WHETHER THE DEVELOPMENT OF ELECTROMOBILITY POSITIVELY INFLUENCES THE QUALITY OF TRANSPORT SERVICES IN CITIES - CRITICAL ANALYSIS

Interest in electromobility among the public has been growing over the last years. In order to determine the impact of the development of electric cars on the quality of urban transport services, factors that may affect the transport of passengers and cargo and related facilities or disadvantages should be analysed. The article presents electromobility characteristics and analyses of conditions related to this modernization. The shortcomings and risks of what is often referred to as the technology of the future - electromobility - are also presented

IS ELECTROMOBILITY IN THE SUPPLY NETWORK A GOOD WAY TO INCREASE INNOVATION?

Interest in electromobility among the public has been growing in recent years. In order to determine the impact of the development of electromobility on the increase in supply network innovation, the situation of the potential use of electric vehicles in the supply network should be analysed, presenting their advantages and disadvantages. The article presents the characteristics of an innovative company operating in the supply network, referring to the electrification of transport. It then presents the electric vehicles currently available on the market for carrying loads, as well as the factors determining the level of innovation of the company in the supply network. The aim of global companies is to minimise the negative impact on the environment through the use of electromobile solutions.Interest in electromobility among the public has been growing in recent years.

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
