Microbe acts as the leading actor in refuse degradation of landfill. Microbial procedure and microbial mechanism of refuse degradation, microbial groups involved, activity of microbes and factors affecting the activity are reviewed and development trend of future research in this area are discussed.

Low temperature sensitivity coefficients are of great significance for improving the combustion stability of modified double-base propellants (MDBPs) under sensitive environmental conditions. In this work, different combined catalyst systems containing Pb-complex, magnesium oxide (MgO), carbon black...

In this paper, the feasibility of treating composite wastewater by Sequencing Batch Reactor (SBR) was studied. The results showed that aeration time influenced the removal efficiency and sludge activity and 10-hour was the optimum duration of aeration for wastewater treatment. When COD in the influe...

Abstract Rare‐allele variants are important for crop improvement because they can be linked to important traits. However, genome‐wide distribution and annotation of rare‐allele variants have not been reported. We analyzed sequencing data from 1556 soybean accessions and found 6,533,419 rare‐allele v...

The development of mammary glands, endocrine hormone concentrations and the gene expression of related receptors were measured in ovariectomized virgin rats after adminstration of an estrogen-like plant extract, rutin. Thirty-two ovariectomized virgin Wistar rats were randomly assigned to 4 treatmen...

Two suites of mafic dykes, T1193-A and T1194-A, outcrop in Gyangze area, southeast Tibet. They are in the area of Comei LIP and have indistinguishable field occurrences with two other dykes in Gyangze, T0902 dyke with 137.7±1.3 Ma zircon age and T0907 dyke with 142±1.4 Ma zircon age reported by Wang...

Phenotypic screening of soybean germplasm suitable for high planting density is currently the most viable strategy to increase yield. Previous studies have shown that soybean varieties with dwarf features and a short petiole often exhibit a compact plant architecture which could improve yield throug...

Soybean yield has traditionally been increased through high planting density, but investigating plant height and petiole traits to select for compact architecture, lodging resistance, and high yield varieties is an underexplored option for further improving yield. We compared the relationships betwe...
