    Get PDF
    The article describes the general characteristics of logistics centres. In particular, their functions, types and characteristics of the model logistics centre were presented. The logistics centres associated in Europlatforms have been described, focusing on those countries where the number of centres is the largest, i.e. Germany, Spain, France and Italy. The factors determining the decision making regarding the selection of the optimal location of a logistics centre in Europe have been discussed, and also the places currently enjoying the greatest interest in the logistics industry have been shown. The development perspectives of Polish logistic facilities are presented and factors influencing the investment attractiveness of Poland are described

    The process of changes in location of the economic centers, changes in commodity exchange and in transport on the world

    The article consists of three parts. First part focuses on the development of goods conveyance (along with the consideration of particular transport branches) between 1980 and 2010 in the United States. Second part describes the development of commodity conveyance by means of transport of particular branches in the European Union in the same year, in Japan (1985-2008) and China (1980-2008). Last part is an attempt to indicate the differences in the structure of transport development in the United States and the European Union

    The Methodology of Research for Elaborating the Concept of High-Speed Rail Construction in Australia – Conclusions for Poland

    Australian economy is considered to be one of the most stable and competitive ones in the world. The country is a trading partner for more than 200 countries, with a 20% share of export in GDP. The economy is mainly based on services which constitute approx. 75% of GDP [1]. According to the UN Human Development Index, Australia is the second country in the world, after Norway, as far as quality and average length of life, health service and freedom of economic activities are concerned. The society’s wealth constitutes one of the key factors that influence the number of cars as per person. The number of cars, which prevail among the passenger means of transport, and their harmful influence on the environment forced the government to focus on limiting the number of private cars by means of, among others, the concept of constructing high-speed rail

    The Analysis of Changes in Exploitation Characteristics of the World Civil Aviation

    Get PDF
    The world economical development at the turn of the century, which gave rise to the possibility of intensification of many economical activity aspects, has resulted in new challenges for civil aviation, in both passenger transport and cargo shipment. In order to satisfy the continually growing demand there is the necessity to enlarge the fleet and modernize the infrastructure being a precondition for the further development of the aviation sector. These processes have so far been inhibited both by financial limitations and construction barriers. The article makes a characterization of separate aircraft producers and the transportation vehicles produced by them. It also presents groups and types of aircrafts popular in different world regions

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

    Get PDF
    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
