| 4 | COVID-19:It's still time for health professionals,physical activity enthusiasts and sportive leagues not to let guard down显示文摘Emerging viral diseases represent a serious issue to public and global healthcare systems and have a high potential for disease dissemination in sport/physical activity and exercise facilities.The Coronavirus disease 2019(COVID-19)pandemic has frightened the sports and physical activity community and enthusiasts for potential trans-mission,dissemination,and lethality in vulnerable populations;those with chronic diseases,co-morbidities,the elderly people,and in young and healthy people.This pandemic has caused a chain reaction with cancellations of sports competitions and gymnasiums closing around the world.Currently,some sporting events are gradually resuming in certain regions of the world and also the return of competitions and training.In general,without fans and public,the sports media can only report the infection of athletes and coaching staff members.However,this situation is dynamic-the world is currently experiencing the second wave of the disease;with the safety and containment measures for the disease is changing daily.The purpose of this article is to present information concerning the COVID-19 pandemic,to clarify health issues for professionals and people connected to sport and physical activity venues,presenting information to assist in educations and the health promotion and prevention.The time is now for making changes,reviewing the actions and conducts necessary for prevention,and most importantly not letting our guard down,even as vaccines become available for all people in the world.Remembering that even after getting vaccinated,it is necessary to continue with safety measures,for example,the use of facial masks and social distance and hygiene,that is,washing your hands frequently and/or sanitizing with 70%alcohol.We can't let our guard down for COVID-19. | Rodrigo L.Vancini Marília S.Andrade Pantelis T.Nikolaidis Beat Knechtle Thomas Rosemann Ricardo B.Viana Claudio A.B.de Lira | 2021 | Sports Medicine and Health Science2021，3，1： | 0 |
| 5 | Application of Amine-Functionalized Cellulose Foam for CO2 Capture and Storage in the Brewing Industry显示文摘Due to a lack of technology,smaller breweries simply dump excess CO2 into the atmosphere,fueling the greenhouse effect and global warming.State-of-the-art CO2 capture technologies using nanofibrillated cellulose are expensive and require laborious freeze-drying.Consequently,there is a high demand for affordable alternatives in order to reduce the environmental impact in this industry sector.This work describes a novel route for a quick and cost-efficient synthesis of amine-functionalized cellulose pellets by a surfactantassisted steam explosion process.Typical values with this method were porosity of 92%and density of 67 g/cm^3.Investigations on polyethylenimine(PEI)content and distribution revealed a maximum PEI concentration of 20 wt%with decreasing concentration to the core of a pellet.Sufficient stability against brewery exhaust gas was determined and CO2 release at^120℃ could be confirmed.Capacity tests under simulated working conditions with a novel laboratory reactor yielded a CO2 capacity of 1.0 mmol/g or 67 mol/m^3,which is comparable to values known from the literature for other cellulose-based adsorbents. | Lars Helmlinger Yejun Zhu Julia Gensel Thomas Neumeyer Stefan Thater Franziska Strube Christoph Bauer Bernd Rosemann Volker Altstadt | 2018 | Journal of Renewable Materials2018，6，3： | 0 |
