1. Large-scale invasions of riparian trees can alter the quantity and quality of allochthonous inputs of leaf litter to streams and thus have the potential to alter stream organic matter dynamics. Non-native saltcedar (Tamarix sp.) and Russian olive (Elaeagnus angustifolia) are now among the most common trees in riparian zones in western North America, yet their impacts on energy flow in stream...

Abstract In order to solve the problem of abnormal wear lower copper row chain TOBSPIN tobacco cutter, working principle compaction unit wire-cutting machine was analyzed. Comprehensive improvements were made system, which effectively reduced on both sides and prolonged usage time chain. Tested with shredder used by Ningbo Cigarette Factory, results showed that speed improved exhaust from 2.62 ...

Adding greenery from public spaces to the co-digestion process with sewage sludge was evaluated by shredding experiments and laboratory-scale batch and continuous mesophilic anaerobic fermentation experiments. The ratio of the shredded grass with 20mm or less in length by a commercially available shredder was 93%. The methane production was around 0.2NL/gVS-grass in the batch experiment. The co...

Little is known about seasonal changes in stream benthic macroinvertebrate assemblages. We determined the ash-free dry mass of macroinvertebrates within a forested and meadow reach Fairbanks Creek northern Lower Michigan throughout all seasons 2018 2019. The assemblage was dominated by invertebrates shredder functional feeding group (FFG), whereas composed primarily scrapers filtering collector...
