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 trace element composition of twelve dinosaur eggshell f

Zooxanthellate corals live in symbiosis with phototrophic dinoflagellates of the family Symbiodiniaceae, enabling the host coral to dwell in shallow, nutrient-poor marine waters.The South Atlantic Ocean is characterized by low coral diversity with high levels of endemism.However, little is known about coral-dinoflagellate associations in the region

Parental empowerment has been related to their well-being and self-efficacy.Learning more about the signs describing child maltreatment risk are crucial for the welfare of children Massage ball and families.The aim of this study was to assess the risk of child maltreatment (CM) and related worrying factors of parents and associations between the CM

Abstract We study a few basic photon- and lepton-initiated processes at the LHC pedal arm set which can be computed using the recently developed photon and lepton parton densities.First, we consider the production of a massive scalar particle initiated by lepton-antilepton annihilation and photon-photon fusion as representative examples of searches

BackgroundIn the past 2 decades, many countries have recognized the use of electronic systems for disease surveillance and outbreak response as an important strategy for disease control and prevention.In low- and middle-income countries, the adoption of these electronic systems remains a priority and has attracted the support of global health playe
