and the air exchange rate is small, improved filtration efficiency masks are needed, to take full advantage of the three fundamental protective mechanisms these masks provide.The Great Recession presented the US with economic and political challenges that had not been experienced since the time of the Great Depression. This article provides a retrospective on the government's response to the crisis ten years after the enactment of the Dodd-Frank Act, as the country is heading into its next presidential election in the midst of yet another downturn, this time fueled by the COVID-19 pandemic.This paper highlights some peculiar characteristics of the economic crisis induced by the spread of COVID-19. It suggests two intertwined policy measures in order to tackle the emergency phase of the crisis and to support the economy in the subsequent recovery phase. The proposed short-term policy measures offer policy responses in the event of a second wave of coronavirus infections in the coming months. In the aftermath of the emergency phase, the current proposal puts forward the implementation of a massive EU-wide recovery plan addressing the long-lasting technological and environmental challenges of these years, which will be financed by European institutions through the issuance of European Pandemic Recovery Bonds.The spread of the coronavirus has made economic conditions difficult in many economic areas and has led to skyrocketing youth unemployment in most European countries. On the basis of simple model calculations, we estimate the consequences of the COVID-19 shutdown on youth unemployment in the European Union for the year 2020. According to our estimations, youth unemployment will increase from 2.8 to 4.8 million. The youth unemployment rate will increase to 26%, and the number of young people not in education, employment and training (NEET) will increase from 4.7 to 6.7 million. Policymakers at the national and international level should react as quickly as possible and make great efforts to avoid these negative scenarios. We suggest the introduction of a new European Youth Guarantee to ensure fiscal relief for those countries that suffer the most economically. It should be financed jointly by the EU and the respective member states. We suggest a new formula-based co-financing model in order to guarantee solidarity between the member states.The coronavirus pandemic led to substantial revisions of 2020 GDP growth projections. We analyse whether and to what extent the quality of government policies in handling the health aspects of the crisis influence cross-country differences in the economic impact of the pandemic as projected by the OECD, the IMF and the World Bank. We measure policy quality by a recently published Economist Intelligence Unit index and a COVID-19 Misery index combining the stringency of government-imposed distancing measures with the COVID-19 fatality rate. Moreover, we control for international spillovers captured by trade openness and export exposure to tourism. Results for most specifications show that good government performance pays off as the respective countries record less severe revisions of growth forecasts. Only in a few cases, our findings suggest that the pandemic's global effect might be so strong that actions by individual governments do not affect cross-country differences of growth revisions. Finally, there is broad evidence supporting the view that a country's exposure to the global economy influences its growth outlook relative to other countries.As a general principle, state aid to firms and sector-specific support schemes should be used only when there are market failures; that is, when there are good reasons to believe that the market would not deliver efficient and/or equitable outcomes.This asymmetric effect of the shock on economic activities becomes an asymmetric impact on countries depending on their sectoral composition.The success of support measures as COVID-19 lockdowns are relaxed depends on the type of recovery the EU wants to achieve.Europe's failure to manage a bold, common response would further increase divergence, strengthen anti-European forces and fuel populism.For the creation of intelligent management systems in hospitals, efficient resource arrangement is essential. Motivated by a real-world scenario in hospitals, we introduce the no-wait two-stage flowshop scheduling problem with the first-stage machine having multi-task flexibility. In this problem, each job has two operations which are processed in order on a two-stage flowshop without preemption and time delay between or on machines. The multi-task flexibility allows the first-stage machine to process the second-stage operations. The goal is to minimize the maximum completion time of all jobs. To the best of our knowledge, this is a pioneering work on this problem. We discover several novel structural properties, based on which we present a linear-time combinatorial algorithm with an approximation ratio 13 8 . This problem and its variants can find many other meaningful applications in modern manufacturing systems, such as the robot cell scheduling with computer numerical control machines or printed circuit boards. The idea behind our algorithm may inspire more practical algorithms.Wastewater released from showers, sinks, and washers contains a considerable amount of waste heat that can be recovered by using a heat exchanger. Conventional metal heat exchangers for wastewater heat recovery have common problems of corrosion, fouling and clogging, which makes it necessary to develop a new type of heat exchanger for such low-grade thermal energy recovery applications. This study deals with a novel patented polymer heat exchanger (WO2020049233A1) made of soft polyurethane tubes that are capable of oscillation once subjected to external forces. MG149 research buy Laboratory tests coupled with theoretical analyses show a stable global heat transfer coefficient of 100-110 W/m2·K, achieving 67-92% of the performance of titanium-, aluminum-, and copper-made heat exchangers with the same configuration. It further reveals that the performance of the soft heat exchanger can be enhanced by 30% when it is under oscillation. In addition, the external convective thermal resistance appears to be the dominant one instead of heat conduction through the wall material.
