The Fluids in Resuscitation of Severe Trauma (FIRST) study meets all of the criteria for assessment as a low risk of bias study, contrary to the unsupported allegations by Bayer and Reinhardt. We dispute the letter from Bayer and Reinhart together with the response from He et al. [1]. Bayer and Reinhart claim that the FIRST study [2] has a high risk of bias and cite two non-peer-reviewed letter...

The present work introduces an extension to three-dimensional Particle Tracking Velocimetry (3-D PTV) in order to investigate small-scale flow patterns. Instead of using monochrome particles the novelty over the prior state of the art is the use of differently dyed tracer particles and the identification of particle color classes directly on Bayer raw images. Especially in the case of a three c...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...

low grade diasporic bauxite in the jajarm mine with an a/s (al2o3/sio2) ratio of 2.3 is not usable in the bayer process at jajarm alumina complex. due to the severe interlocking effect between the diaspore and aluminosilicate minerals (chamosite and kaolinite) and iron-containing minerals in a microcrystal matrix, the thermo-chemical treatment, which is independent from micro-mineralogy, was ch...
