Implementation of a comprehensive ice crystal formation parameterization for cirrus and mixed-phase clouds in the EMAC model (based on MESSy 2.53)
2018
A comprehensive ice nucleation parameterization has been implemented in the global chemistry-climate model EMAC to improve the representation of ice crystal number concentrations (ICNCs). The parameterization of Barahona and Nenes (2009, hereafter BN09) allows for the treatment of ice nucleation taking into account the competition for water vapour between homogeneous and heterogeneous nucleation in cirrus clouds. Furthermore, the influence of chemically heterogeneous, polydisperse aerosols is considered by applying one of the multiple ice nucleating particle parameterizations which are included in BN09 to compute the heterogeneously formed ice crystals. BN09 has been modified in order to co…
Impact of the Coronavirus pandemic on the economic development of Ukraine and Latvia
2021
The COVID-19 pandemic that has swept the world has created a number of diverse threats to the development of the countries’ economies, including Ukraine and Latvia. An adequate assessment of these threats is very difficult and, moreover, often has a probabilistic character due to their singularity and novelty. The COVID-19 crisis mainly affected the tertiary sector, in particular companies involved in tourism, international passenger transport, accommodation, catering, entertainment, and cultural events, where demand fell sharply, and jobs fell. They were also followed by a contraction in demand in the manufacturing and transport sectors, which were mainly oriented towards external demand a…
A Snapshot of the World of Global Multinationals – An Industry Based Analysis of Fortune Global 500 Companies
2017
Abstract For better or for worse, the “corporations rule the world” assertion is nowadays more actual and accurate than ever before, as multinational companies represent the undisputable engine of the globalization process, and the latter continuously (re)creates the background against which global multinationals are flourishing, while reinforcing their “domination”. Since 1995, the Fortune Global 500 ranking (FG 500) annually provides a comprehensive and eloquent image of the world of global multinationals; the merits of the FG 500 ranking go beyond the synchronic approach of the characteristics of global multinationals (in terms of revenues, profits, assets and employees - by sector, indu…
PRICE CONVERGENCE IN THE EUROPEAN CAR MARKET
2008
International audience; This paper examines price convergence in the European Union car market over the period 1995-2005. We find that there is a clear evidence of price convergence among the EU15 countries, but not before 1999. Moreover, countries of the Economic and Monetary Union (EMU) started convergence previously to the EU15 as a whole. Finally, exchange rate changes have significantly contributed to price dispersion over time across countries. The results provide significant evidence that trade liberalization and the EMU have enhanced the process of regional integration in the European automobile industry, even though there is room for further measures to promote integration.
Forecasting container transshipment in Germany
2009
International audience; In this paper, we examine container transshipment at German ports using the seasonal ARIMA (SARIMA) model and the Holt-Winters exponential smoothing approach. Our models are designed especially to take account of the seasonal behavior of the quarterly data used. We consider the dynamic development in this sector for the whole container throughput and also the destinations Asia, Europe and North America, which are the world's three main economic regions. Our data runs from the first quarter of 1989 to the fourth quarter of 2006. We provide detailed quarterly forecasts for the year 2007 and 2008. According to forecasting error measures such as Mean Square Error and The…
New Physics adventures in the LHC age
2017
La física de partículas está viviendo actualmente una era de exploración que comenzó con la observación en el LHC del bosón de Higgs, proporcionando así al Modelo Estándar de la Física de Partículas la elusiva pieza final que lo completa. Si bien esta teoría es extremadamente exitosa, se acepta comúnmente que no es la teoría final ya que no puede responder a todas las preguntas teóricas ni a ciertas observaciones experimentales. Por lo tanto, se espera que Nueva Física que extienda al Modelo Estándar aparezca pronto, aunque esto bien podría ser sólo una esperanza. Esta tesis recoge algunas de las aventuras en la búsqueda de Nueva Física. Se organiza en tres partes: la Parte I introduce, en …

Określono wpływ działalności pozarolniczej na jakość życia ludności wiejskiej oraz przedstawiono przykłady aktywizacji i różnych działań kreatywnych będących formą przedsięwzięć innowacyjnych na obszarach wiejskich województwa opolskiego.
Reheating the Standard Model from a hidden sector
2016
We consider a scenario where the inflaton decays to a hidden sector thermally decoupled from the visible Standard Model sector. A tiny portal coupling between the hidden and the visible sectors later heats the visible sector so that the Standard Model degrees of freedom come to dominate the energy density of the Universe before Big Bang Nucleosynthesis. We find that this scenario is viable, although obtaining the correct dark matter abundance and retaining successful Big Bang Nucleosynthesis is not obvious. We also show that the isocurvature perturbations constituted by a primordial Higgs condensate are not problematic for the viability of the scenario.
Prospects of searching for (un)particles from Hidden Sectors using rapidity correlations in multiparticle production at the LHC
2008
Most signatures of new physics have been studied on the transverse plane with respect to the beam direction at the LHC where background is much reduced. In this paper we propose the analysis of inclusive longitudinal (pseudo) rapidity correlations among final-state (charged) particles in order to search for (un)particles belonging to a hidden sector beyond the Standard Model, using a selected sample of p-p minimum bias events (applying appropriate off-line cuts on events based on, e.g. minijets, high-multiplicity, event shape variables, high-p(perpendicular to) leptons and photons, etc.) collected at the early running of the LHC. To this aim, we examine inclusive and semi-inclusive two-part…
Reti, Nuovi Settori e Sostenibilità
2014
Negli ultimi anni, anche a seguito del perdurare della crisi economica, gli studiosi delle diverse discipline, ivi compresi gli scienziati regionali, si sono interrogati su come riconnettersi a un sentiero virtuoso di crescita economica e sociale ai diversi livelli territoriali. Non vi è dubbio che la crisi abbia stimolato, in molti ambiti, la scoperta di nuovi paradigmi o la rivalutazione di schemi concettuali che stentavano ad affermarsi. Partendo da tale premessa, l’oggetto di questo volume è proprio quello di riflettere su come alcuni di questi nuovi paradigmi (in tema di reti, nuovi settori, sostenibilità) abbiano orientato l’indagine empirica territoriale e di raccogliere ed evidenzia…
