Based on the data of global mineral production and ore recovery in mining processing, this paper presents annual 25 minerals calculates losses 20 from year 1920 to 2018. The results indicate that 23 has increased by between 1 930 times since 1920, similar increase GDP per capita 1960. At same time, a vast amount been lost processing 1920. Hence, discusses possibility increasing ratio.

Introduction 2 • PTIME decidable uniform word problems for quasi-varieties • CS applications: type inference systems, program analysis, decision procedures in ATP • fundamental effective methods for establishing PTIME upper bounds • local theories (Givan, McAllester 92) capture PTIME • algebraic criteria by Skolem (1920), Evans (1951), and Burris (1995) • relation between these criteria Introdu...

The Spanish influenza pandemic in the years 1918-1920 was the largest and most tragic pandemic of infectious disease in human history. Deciphering the structure of the virus (including the determination of complete genome sequence) of this pandemic and the phylogenetic analysis and explanation of its virulence became possible thanks to molecular genetic analysis of the virus isolated from the f...
