Influenza virus nucleoprotein (NP) is the major component of the viral ribonucleoprotein complex, which is crucial for the transcription and replication of the viral genome. We have determined the crystal structure of influenza B virus NP to a resolution of 3.2 Å. Influenza B NP contains a head, a body domain, and a tail loop. The electropositive groove(More)
This paper introduced a modified algorithm from two dots algorithm path planning for soccer robot. The modified algorithm can predict the position of obstacles emerged more accurately, and effectively reduce the region that obstacles may arise, so the robot path planning can be more quickly and efficiently than the two dots algorithm. This paper also(More)
OBJECTIVE We aimed to select a stable lactic acid bacteria community from switchgrass silage, that was efficient in lactic acid production. METHODS We obtained the community by continuous restricted subcultivation in MRS broth, and analysed the composition diversity and stability of the community by 16S rRNA gene-based pyrosequencing and Denaturing(More)
Six leaf traits, i.e., fresh mass (FM), dry mass (DM), leaf dry matter content (DMC), area (AR), specific leaf area (SLA) and thickness (TH) from 23 plant species in the southeastern Keerqin Sandy Lands, China were measured. The results show that leaf traits of herbs were more diversified than those of shrubs and trees and average SLA tended towards a(More)
Silage processing has a crucial positive impact on the methane yield of anaerobic treated substrates. Changes in the characteristics of switchgrass after ensiling with different additives and their effects on methane production and microbial community changes during anaerobic digestion were investigated. After ensiling (CK), methane yield was increased by(More)
Clostridium straminisolvens (CSK1) is a novel cellulolytic bacterium isolated from a cellulose-degrading bacterial community MC1. In this study, the influence of the following cell disruption and elution methods on CSK1cellulase release was investigated: (1) freezing-thawing, (2) ultrasonication, (3) elution, (4) freezing-thawing following elution, (5)(More)
The objective of this paper was to assess the congruency of leaf traits and soil characteristics and to analyze the survival strategies of different plant functional types in response to drought and nutrient-poor environments in the southeastern Ke’erqin Sandy Lands in China. Six leaf traits-leaf thickness (TH), density (DN), specific leaf area (SLA), leaf(More)
