Following an observational study design, the data on subjective wellbeing (life satisfaction) are derived from the integrated EVS and WVS dataset (1990–2014) [31], which covers 77 countries (see Appendix 1). The repeated cross-sectional data set consists of approximately 506,000 individual respondents from different countries. The survey sample size ranges from 1200 to 1500. Data collection is conducted through face-to-face interviews at respondent’s residences.

Abstract The material targeted in this study is TEPEX® flowcore, a long glass fiber mat reinforced polyamide (PA6/GF) manufactured by Lanxess. The material is classified experimentally on coupon level, and the kinetic behavior is analyzed through standard and flash DSC analyses. Subsequently, results from experimental molding trials are investigated concerning material forming and material flow.

Abstract Invasion by nonnative annual plants that form prolific seed banks, including Bromus tectorum L. (cheatgrass), throughout western North America is a major natural resource concern. Even with known economic and ecological implications, soil seed banks and their potential to impact ecological restoration in arid and semiarid ecosystems are poorly understood.
