Composite material recycling technology—state-of-the-art and sustainable development for the 2020s

2021

Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the first major wave of composite wind turbines reaching their End-of-Life (EoL) and being decommissioned in 2019–2020, (3) the acceleration of aircraft decommissioning due to the COVID-19 pandemic, and (4) the increase of composites in mass production cars, thanks to the development of high volume technologies based on thermoplastic composites. Such sociotechnical pressure will only grow in the upcoming decade of 2020s as other countries are to follow Germany by limiting and ba…

Эволюция орбит комет

1963

Latviešu astronoms Kārlis Šteins (1911 – 1983) pētīja komētu orbītu difūziju – mazu izmaiņu uzkrāšanos orbītas parametra – lielās pusass apgrieztajās vērtībās. Kopā ar līdzstrādniekiem viņš modelēja daudzu komētu orbītas un noteica, kā Jupitera gravitācijas spēks ietekmē lielo pusasu apgrieztos lielumus un vēl vienu orbītas parametru – perihēlija attālumu. Viņi ieguva un atrisināja diferenciālvienādojumu, kas apraksta komētu difūziju. Pētījumos K. Šteins atklāja jaunas orbītu parametru statistiskās sakarības, kas literatūrā pazīstamas kā komētu difūzijas likumi un reizēm tiek sauktas viņa vārdā. Šie pētījumi apkopoti viņa fizikas un matemātikas zinātņu doktora disertācijā „Komētu orbītu evo…
