TRACE ELEMENT DETERMINATION OF LATE CRETACEOUS DINOSAUR EGGSHELL FOSSILS FROM XIXIA BASIN, HENAN PROVINCE BY ICP-OES AND ITS IMPLICATIONS FOR EXTINCTION OF DINOSAURS

Dinosaur egg fossils are important for exploring the survival and extinction of the dinosaurs.Current researches on dinosaur egg fossils are concentrated in their biology and burial features.In this study, Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) was used to determine Pucks trace element composition of twelve dinosaur eggs

Human relationships will not be able to escape with the natural ecosystem.Humans and natural ecosystems coexist in a balanced portion so that no gaps occur.A reciprocal relationship between human life and the natural ecosystem occurs.However, the relationship between humans and the natural Slate Decoration ecosystem becomes unhealthy because the hu

Abstract Background Tumor neoantigen peptide-based vaccines, systemic immunotherapies that enhance antitumor immunity by activating and expanding antigen-specific T cells, have achieved remarkable results in the treatment of a variety of solid tumors.However, how to effectively deliver neoantigens to induce robust antitumor immune responses remains

Enhanced dielectric and mechanical properties of polyarylene ether nitrile (PEN) are obtained through secondary dispersion of polyaniline functionalized barium titanate (PANI-f-BT) by hot-stretching.PANI-f-BT nanoparticles with different PANI content are successfully prepared via in-situ aniline polymerization technology.The transmission electron d

Florida nursery operators need to understand plant propagation principles and techniques so they can grow enough plants for sale.Micropropagation is a way to culture plant tissue to rapidly Shoes propagate a large number of plants.This 4-page fact sheet presents an overview of micropropagation to help growers evaluate it as a propagation technique
