TEACHING THE HISTORY OF MICROBIOLOGY AND THE TRANSFORMATION OF THE LABORATORY: A STUDY IN MINIATURE


An Environment-Friendly Process Featuring Calcified Roasting and Precipitation Purification to Prepare Vanadium Pentoxide from the Converter Vanadium Slag

Converter vanadium slag is a byproduct of the iron making process when the vanadium titanomagnetite is used as iron raw material.A cleaner process including calcified roasting, dilute acid leaching, precipitation purification, vanadium precipitation with ammonium salt, followed by thermal decomposition was proposed to extract vanadium resource from

On spinor construction of Bertrand curves

Spinors MAG W K permeate all of modern physics and have also an important place in mathematics.Spinors are used intensively in modern theoretical physics and differential geometry.In this study, spinors are used for a different representation of differential geometry in E3.The goal of this study is also the spinor structure lying at the basis of di
