Radiotracer experiments are carried out in order to determine the mean residence time (MRT) as well as percentage of dead zone, V dead (%), in an integrated mixer consisting of Rushton and pitched blade turbine (PBT). Conventionally, optimization was performed by varying one parameter and others were held constant (OFAT) which lead to enormous number of experiments. Thus, in this study, a 4-fac...

The net absorption of fluid and electrolytes by the mammalian small intestine may be changed to a state of net secretion by the administration of agents that elevate the cyclic AMP content of the mucosal epithelium, e.g. cholera toxin, theophylline, dibutyrylcyclic AMP [for reviews see Banwell &Sherr(1973),Sladen(1973), Field(1974) and Kimberg (1974)l. In contrast with the wealth of data on the...

Transport and metabolism of IAA-1-(14)C in Coleus blumei Benth. was studied by means of a combination of liquid scintillation counting, autoradiography and thin-layer chromatography. Transport of IAA in petiole segments of increasing age (No. 2-8) was strictly polar in a basipetal direction. No acropetal movement occurred in either young or old tissues. The greatest amount, expressed as a perce...

One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the accident cause makes the selection of high accident prone segments inaccurate. In this paper, by...

In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...

Battery Recycling In article number 2211946, Bartosz A. Grzybowski and co-workers present a one-pot separation of metals from spent lithium-ion batteries. Three liquid layers occupy different segments the rotating cylindrical vessel are intensely stirred to move selected components between layers. only ten minutes, all cobalt manganese migrate feed acceptor layer (red), while lithium nickel rem...
