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

The purpose of this paper is to identify the variables that determine or explain the supply of bounced checks, either issued in Lebanese pounds or issued in US dollars.This is an area that the extant empirical research fails to cover, and hence, this paper is, by itself, quite innovative.Four major explanatory variables are identified.Two of them a

Abstract Clinical features of sudden sensorineural hearing loss (SSNHL) associated with vestibular schwannoma (VS) are not fully understood.Determining a treatment plan and explaining it to patients requires clinicians to clearly understand the clinical features related to the tumor, including SSNHL.To identify the full range of clinical features o

Corn was used as the research socialstudiesscholar.com material, based on gas chromatography ion mobility spectroscopy (Gc-IMS) and gas chromatography-mass spectrometry (GC-MS), the odor fingerprints of corn were analyzed under 9 different treatments, including frying, steaming, boiling, quick freezing, precooling, freeze-drying, bleaching and dyei

Introduction and purpose: Due to the increasing consumption of fried foods, it is important to check the quality of the oil used for frying to maintain the health of consumers.Therefore, this study aimed to determine the amount of peroxide, acidity, and thermal stability of the oils used in Falafel stores in Arak, Iran.Methods: This cross-sectional
