Non-grain production of cultivated land (NGPCL) is an essential factor that affects food security and sustainable agricultural development. Due to the large population limited area present in China, resources are more extensive valuable hilly mountainous areas, though expansion NGPCL threatens detrimental use resources. To better understand problem this paper initially classifies into four dist...

Abstract This study aimed to investigate the effect of epoxidation levels on curing and tensile properties epoxidized natural rubber (ENR)/microfibrillated cellulose (MFC) composites. ENRs with different were first prepared from (NR) latex via ‘in situ ’ performic using 0.75 M formic acid 1 hydrogen peroxide at 50°C various reaction times. The results H NMR revealed that 2, 4, 6 hours could ach...

Microalgae-based antibiotic removal treatment has attracted attention because of its low carbon and sustainable advantages. The microalgal co-metabolism system with a suitable source leads to enhanced performance pollutant removal. However, currently, limited knowledge is available for the fluoroquinolone using microalgae-mediated system. In this study, we first investigated that biotic process...

Each Carnegie Mellon course number begins with a two-digit prefix which designates the department offering the course (76-xxx courses are offered by the Department of English, etc.). Although each department maintains its own course numbering practices, typically the first digit after the prefix indicates the class level: xx-1xx courses are freshmen-level, xx-2xx courses are sophomore level, et...

In these notes “homology manifold” means ENR (Euclidean neighborhood retract) Z–coefficient homology manifold, unless otherwise specified, and “exotic” means not a manifold factor (ie local or “Quinn” index 6= 1. We use the multiplicative version of the local index, taking values in 1+8Z). In the last decade exotic homology manifolds have been shown to exist and quite a bit of structure theory ...
