The genus Pallisentis has been mostly found among the freshwater fishes of Channidae family. ophiocephali is characterized with some unique characters proboscis, hooks, and spines. However, initial description a little sketchy yet not updated. present study communicates detail morphology an acanthocephalan species obtained from two host family—Channa striatus Channa punctatus—during one-year su...

Public bulletin boards are widely used in various public places, but due to the large size of billboards, it is not easy carry, and traditional billboards integrated, when need be transferred, limited storage space vehicle needs occupied It extremely inconvenient, at night, install additional light sources illuminate them, which greatly increases energy consumption. Based on this paper designed...

Lower termites harbor diverse consortia of symbiotic gut flagellates. Despite numerous evidence for co-cladogenesis, the evolutionary history these associations remains unclear. Here, we present Retractinymphidae fam. nov., a monogeneric lineage Trichonymphida from Serritermitidae. Although Retractinympha glossotermitis gen. nov. sp. morphologically resembles members genus Pseudotrichonympha , ...

The current situation of the epidemic is complex and changeable. Under China adherence to “dynamic zero clearance,” prevention control closely related all walks life, awning has become one essential basic facilities. However, most awnings are manufactured for isolation protection from wind rain, which could not meet needs electricity allocation during emergencies. Therefore, our goal design a n...

A novel rigid deployable aeroshell architecture has been developed, where panels with a thermal protection system layer are connected between retractable ribs. Following origami principles, an optimal fold pattern is selected and imposed on the to ensure efficient flat stowage during launch repeatable deployment. The design process includes minimizing number of folds reduce stacking height maxi...
