Furthermore, the mass of a copper atom is 63.57 times the mass of a hydrogen atom (which is 1.63×10−24 g) so that the mass of 1 m3 of copper, i.e. the density, is 8.56×1028×63.57×1.63×10−24=8900 kg m−3. On alloying, the density of a metal changes. This is ...
Background & aims: Measuring of the relative exchangeable copper seems to be a promising tool for the diagnosis of Wilson disease. The aim of our study is to determine the performance of REC for the diagnosis of Wilson disease in a population of patients with chronic liver diseases. Methods:...
We present elemental and Sr–Nd–Pb isotopic data for the magmatic suite (~79 Ma) of the Harşit pluton, from the Eastern Pontides (NE Turkey), with the aim of determining its magma source and geodynamic evolution. The pluton comprises granite, granodiorite, tonalite and minor diorite (SiO...

These adjectives refer literally to what is capable of withstanding stress without damage and figuratively to what can undergo change or modification:a flexible wire; flexible plans; an elastic rubber band; an elastic interpretation of the law; thin, resilient copper; a resilient temperament; supple...
White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of white vinegar is 1.007 g/cm3, what is the pH? The ionization constant of lactic acid, CH3CH(OH)CO2H, an acid found in the blood after strenuous exercise, is 1.36 × 10−4. If 20.0 g of lactic...
relative mass. Number of beans in 1 relative mass = bean one of mass Average Mass Relative 6. Check your calculated results by adding beans to a cup of known mass until the total mass of the beans in the cup is equal to the sum of the mass of the cup and the relative mass of ...
To analyse the relative and combined effects of ethanol and a low protein diet on bone copper and manganese, and their relationships with bone structure and metabolism, including trabecular bone mass (TBM), osteoid area (OA), osteocalcin (OCN), insulin-like growth factor-1 (IGF-1), ...
