REANALYSIS OF WUPUS AGILIS (EARLY CRETACEOUS) OF CHONGQING, CHINA AS A LARGE AVIAN TRACE: DIFFERENTIATING BETWEEN LARGE BIRD AND SMALL NON-AVIAN THEROPOD TRACKS.

Trace fossils provide the only records of Early Cretaceous birds from many parts of the world.The identification of traces from large avian track-makers is made difficult given their overall similarity in size and tridactyly in comparison with traces of small non-avian theropods.Reanalysis of Wupus agilis from the Early Cretaceous (Aptian-Albian) J

Crystalline films of syndiotactic polystyrene (s-PS), a commercially available thermoplastic polymer, having a highly hydrophilic amorphous phase, were achieved by using a Universal Simmerstat mild solid-state sulfonation procedure.Despite the used mild process conditions, an easy and uniform sulfonation of the phenyl rings of the amorphous phase i

In this paper, a new two-stage approach has been presented for the reactive power control of power systems.In the first stage, the transmission network is divided into several parts using a partitioning approach based on graph concept.In the second stage, a hierarchical distributed framework based on a System of Systems (SoS) concept has been propo

Background and aims: With a widespread regard to the human error issue and recognize the importance of human as an active processor of Bath Soaks information The necessity for an effective framework to analyze different mental processes interact with the system to carry out job duties will be obvious.So the aim of this study was to analyze human er

Organismal traits and their evolution can strongly influence food web structure and dynamics.To what extent the Shoe Care evolution of such traits impacts food web structure, however, is poorly understood.Here, we investigate a simple three-species omnivory food web module where the attack rates of all predators evolve as ecological dynamics unfold
