How important is the relaxation of contact restrictions for the recovery of the German economy and what conclusions can be drawn for the appropriate level of contact restrictions in the coming months? In considering these issues, an attempt will be made to assess what significance the contact restriction measures introduced by the federal and state governments since mid-March 2020 will actually have for the current slump in economic activity in Germany. In addition, the various plausible scenarios for the spread and containment of infection are presented with different options for easing contact restrictions. © Der/die Autor(en) 2020.The fight against the coronavirus pandemic has led to an insulation of social and economic life and will have considerable economic consequences. Important areas of the industry and service sectors were partially or completely shutdown. A resumption of activity should happen as soon as possible, once the medical pre-conditions have been established and are met. This requires a clear exit strategy and following several steps to return to previous welfare and growth data levels. After securing survival during this crisis via various liquidity lines and bridging loans, the economy's restart requires the relaunch of public infrastructure, especially of schools and kindergartens. To facilitate a coordinated and synchronised restart of complex industrial value chains, we need clear signals on a planned schedule. A tax policy driven departure signal and a demand side focused growth programme could make an important contribution to a new economic dynamic after the crisis. © Der/die Autor(en) 2020.The authors model the evolution of the number of confi rmed cases of COVID-19 in Germany. Their theoretical framework builds on a continuous time Markov chain with four physical states healthy, sick, recovered or asymptomatic infected, and dead. Their quantitative solution matches the number of sick individuals based on the most recent fi gures with the share of sick individuals following from infection rates and sickness probabilities. They employ this framework to study the expected peak of the number of sick individuals in a scenario without public regulation of social contacts. They also study the impact of public regulations. For all scenarios, they report the expected end of the COVID-19 epidemic. © Der/die Autor(en) 2020.The explosion of Covid-19 cases is looming in Germany. The German Society for Epidemiology has warned that the number of cases could soon overshoot the capacity of the healthcare system. This may be true even if Germany follows the 'flatten-the-curve'- approach to reduce infection rates. A suppression of the virus remains the best solution for the crisis. Supply will suffer as long the virus persists. Until then, demand side measures will not cure the epidemic. Coordinated measures for business that ensure compliance and European debt instruments may be part of a strategy to solve the crisis. © Der/die Autor(en) 2020.The corona crisis started in China and had great consequences for public health and the economy. In the meantime, high and rapidly growing numbers of cases of infections with SARS-CoV-2 have also been recorded in Japan, Korea, Italy, Germany, Great Britain, France, Spain and above all in the USA. Forecasts of economic growth have been massively revised downwards and governments around the world are struggling to find the right economic policy response. This article describes basic short-term options for the German government to react to the corona shock and briefl y assesses the package of measures "Schutzschirm für Beschäftigte und Unternehmen" presented on 13 March 2020 by the German Finance Minister Olaf Scholz and the German Economics Minister Peter Altmaier. © Der/die Autor(en) 2020.According to the leading German economic research institutes, the German economy is experiencing a drastic slump as a result of the corona pandemic. In order to slow down the wave of infection, the state has severely restricted economic activity in Germany. As a result, GDP is expected to shrink by 4.2% this year. The recession is leaving clear traces on the labour market and the national budget. At its peak, the unemployment rate will soar to 5.9% and the number of short-time workers to 2.4 million. This year, the fiscal policy stabilisation measures will lead to a record deficit in the general government budget of 159 billion euro. After the shutdown, the economy will gradually recover. Accordingly, the increase in GDP next year will be strong at 5.8%. This forecast is associated with considerable downside risks, e.g. because the pandemic can be slowed faster or because the recovery of economic activity will be less successful than expected or there may be a new wave of infection. see more © Der/die Autor(en) 2020.During childhood several adenovirus infections have to be experienced, each with another of the multiple types. The spectrum of associated diseases ranges from endemic, mild and self-limiting upper respiratory tract infections to epidemic gastroenteritis, eye infections, cystitis and less frequently atypical pneumonia and severe infections of internal organs; however, the vast majority of adenovirus infections during childhood are not life threatening with the exception of the infrequent infections of neonates and the frequent infection of hematopoietic stem cell recipients (disseminated disease). © Springer Medizin Verlag GmbH, ein Teil von Springer Nature 2020.The crystal and molecular structure and physicochemical properties of 2-N-methylamino-3-methylpyridine N-oxide (MA3MPO) have been studied. MA3MPO was synthesized from 2-amino-3-methylpyridine by several steps to form colorless crystals suitable for crystallographic analysis. The data reveal that MA3MPO crystallizes in the monoclinic space group P21/n. The studied compound contains a nearly flat triply substituted pyridine skeleton whose structure is stabilized by an intramolecular N-H⋅⋅⋅O hydrogen bond. The N-oxide molecules are connected together by weak C-H⋯O hydrogen bonds, an acceptor of which is the oxygen atom from the N-oxide group. This leads to creation of two-dimensional network of hydrogen bonds. Its IR, Raman, UV-Vis and luminescence spectra have been measured and analyzed on the basis of DFT and NBO quantum chemical calculations in which the B3LYP/6-311++G(d,p) approach was applied. The distribution of the electron levels in the studied compound has been analyzed in terms of the possibility of its participation in the ligand-to-lanthanide ion energy transfer.
