It is assumed that student awareness of STEM education and STEM fields will increase after they encounter the concept of STEM education in their field education courses which are taught in the first two years of the Science Education College curriculum as determined by the Turkish Council of Higher...

Goethite forms by precipitation from solution after ferrihydrite dissolution, while hematite formation is preceded by ferrihydrite aggregation and hematite nucleation within these aggregates as a solid phase reaction8,10. However, it is proposed recently that goethite rods can be formed from ferrihydrite ...

Hematite formation from ferrihydrite is a solid-phase reaction, while goethite is precipitated from solution after ferrihydrite dissolution. Magnetic fields are interpreted to accelerate ferrihydrite aggregation via a ferrimagnetic intermediate phase. This implies that the effect of geomagnetic field intensity...
After years of hard work, Chinese scientists have mastered a complete set of technologies for purifying raw materials and directly drawing plastic optical fibers through bulk polymerization. The Institute of Physics and Chemistry of the Chinese Academy of Sciences has successfully developed a full-automa...

However, as the magnetic field during the QGP stage of the evolution is expected to be small compared to that of the pre-equilibrium stage, it is likely that CME production after the pre-equilibrium stage is negligible. It was also argued in Ref. [39] that the sphaleron rate out of ...
(seeAppendix), and a standardized test on spatial abilities was administered. In the subsequent eye-tracking phase, after successful calibration (see Section3.4), participants were given a short written introduction to the topic of vector fields before they had to solve eight coordination tasks. In...
